+@appendix Packet Binary Dump Format
+
+  Zebra can dump routing protocol packet into file with a binary format
+(@pxref{Dump BGP packets and table}).
+
+  It seems to be better that we share the MRT's header format for
+backward compatibility with MRT's dump logs. We should also define the
+binary format excluding the header, because we must support both IP
+v4 and v6 addresses as socket addresses and / or routing entries.
+
+  In the last meeting, we discussed to have a version field in the
+header. But Masaki told us that we can define new `type' value rather
+than having a `version' field, and it seems to be better because we
+don't need to change header format.
+
+  Here is the common header format. This is same as that of MRT.

+There are five routing daemons in use, and there is one manager daemon.
+These daemons may be located on separate machines from the manager
+daemon.  Each of these daemons will listen on a particular port for
+incoming VTY connections.  The routing daemons are:
+
+@itemize @bullet
+@item @command{ripd}, @command{ripngd}, @command{ospfd}, @command{ospf6d}, @command{bgpd}
+@item @command{zebra}
+@end itemize

+The following sections discuss commands common to all the routing
+daemons.

+
+
+In a config file, you can write the debugging options, a vty's password,
+routing daemon configurations, a log file name, and so forth. This
+information forms the initial command set for a routing beast as it is
+starting.
+
+Config files are generally found in:
+
+@itemize @asis
+@item @file{@value{INSTALL_PREFIX_ETC}/*.conf}
+@end itemize
+
+Each of the daemons has its own
+config file.  For example, zebra's default config file name is:
+
+@itemize @asis
+@item @file{@value{INSTALL_PREFIX_ETC}/zebra.conf}
+@end itemize
+
+The daemon name plus @file{.conf} is the default config file name. You
+can specify a config file using the @kbd{-f} or @kbd{--config-file}
+options when starting the daemon.

+
+
+Below is a sample configuration file for the zebra daemon.
+
+@example
+@group
+!
+! Zebra configuration file
+!
+hostname Router
+password zebra
+enable password zebra
+!
+log stdout
+!
+!
+@end group
+@end example
+
+'!' and '#' are comment characters.  If the first character of the word
+is one of the comment characters then from the rest of the line forward
+will be ignored as a comment.
+
+@example
+password zebra!password
+@end example
+
+If a comment character is not the first character of the word, it's a
+normal character. So in the above example '!' will not be regarded as a
+comment and the password is set to 'zebra!password'.

+stop}.
+
+The file name is an run-time option rather than a configure-time option

+useful when using Zebra to implement a routing looking glass.  One

+@subsection VTY Overview
+
+
+VTY stands for Virtual TeletYpe interface.  It means you can connect to
+the daemon via the telnet protocol.
+
+To enable a VTY interface, you have to setup a VTY password.  If there
+is no VTY password, one cannot connect to the VTY interface at all.
+
+@example
+@group
+% telnet localhost 2601
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.

+4 (BGP-4)}.
+
+  Many extentions are added to @code{RFC1771}.  @code{RFC2858} -

+
+  First of all you must configure BGP router with @command{router bgp}

+for detecting whether the BGP connection is internal one or external one.

+Enable a BGP protocol process with the specified @var{asn}.  After

+specifying @code{multiple-instance} (@pxref{Multiple instance}).

+This command specifies the router-ID.  If @command{bgpd} connects to @command{zebra} it gets
+interface and address information.  In that case default router ID value
+is selected as the largest IP Address of the interfaces.  When
+@code{router zebra} is not enabled @command{bgpd} can't get interface information

+
+  BGP communities attribute is widely used for implementing policy
+routing.  Network operators can manipulate BGP communities attribute
+based on their network policy.  BGP communities attribute is defined
+in @code{RFC1997} - @cite{BGP Communities Attribute} and
+@code{RFC1998} - @cite{An Application of the BGP Community Attribute
+in Multi-home Routing}.  It is an optional transitive attribute,
+therefore local policy can travel through different autonomous system.
+
+  Communities attribute is a set of communities values.  Each
+communities value is 4 octet long.  The following format is used to
+define communities value.
+
+@table @code
+@item AS:VAL
+This format represents 4 octet communities value.  @code{AS} is high
+order 2 octet in digit format.  @code{VAL} is low order 2 octet in
+digit format.  This format is useful to define AS oriented policy
+value.  For example, @code{7675:80} can be used when AS 7675 wants to
+pass local policy value 80 to neighboring peer.
+@item internet
+@code{internet} represents well-known communities value 0.
+@item no-export
+@code{no-export} represents well-known communities value @code{NO_EXPORT}@*
+@r{(0xFFFFFF01)}.  All routes carry this value must not be advertised
+to outside a BGP confederation boundary.  If neighboring BGP peer is
+part of BGP confederation, the peer is considered as inside a BGP
+confederation boundary, so the route will be announced to the peer.
+@item no-advertise
+@code{no-advertise} represents well-known communities value
+@code{NO_ADVERTISE}@*@r{(0xFFFFFF02)}.  All routes carry this value
+must not be advertise to other BGP peers.
+@item local-AS
+@code{local-AS} represents well-known communities value
+@code{NO_EXPORT_SUBCONFED} @r{(0xFFFFFF03)}.  All routes carry this
+value must not be advertised to external BGP peers.  Even if the

+@subsection BGP Community Lists
+
+  BGP community list is a user defined BGP communites attribute list.
+BGP community list can be used for matching or manipulating BGP
+communities attribute in updates.
+
+  There are two types of community list.  One is standard community
+list and another is expanded community list.  Standard community list
+defines communities attribute.  Expanded community list defines
+communities attribute string with regular expression.  Standard
+community list is compiled into binary format when user define it.
+Standard community list will be directly compared to BGP communities
+attribute in BGP updates.  Therefore the comparison is faster than
+expanded community list.
+
+@deffn Command {ip community-list standard @var{name} @{permit|deny@} @var{community}} {}
+This command defines a new standard community list.  @var{community}
+is communities value.  The @var{community} is compiled into community
+structure.  We can define multiple community list under same name.  In
+that case match will happen user defined order.  Once the
+community list matches to communities attribute in BGP updates it
+return permit or deny by the community list definition.  When there is
+no matched entry, deny will be returned.  When @var{community} is
+empty it matches to any routes.
+@end deffn
+
+@deffn Command {ip community-list expanded @var{name} @{permit|deny@} @var{line}} {}
+This command defines a new expanded community list.  @var{line} is a

+regular expression to match communities attribute in BGP updates.

+
+@deffn Command {no ip community-list @var{name}} {}
+@deffnx Command {no ip community-list standard @var{name}} {}
+@deffnx Command {no ip community-list expanded @var{name}} {}
+These commands delete community lists specified by @var{name}.  All of
+community lists shares a single name space.  So community lists can be
+removed simpley specifying community lists name.

+standard community list.  Community list number in the range from 100
+to 199 is expanded community list.  These community lists are called
+as numbered community lists.  On the other hand normal community lists
+is called as named community lists.
+
+@deffn Command {ip community-list <1-99> @{permit|deny@} @var{community}} {}

+@subsection Using BGP Communities Attribute
+
+  Following configuration is the most typical usage of BGP communities
+attribute.  AS 7675 provides upstream Internet connection to AS 100.
+When following configuration exists in AS 7675, AS 100 networks
+operator can set local preference in AS 7675 network by setting BGP
+communities attribute to the updates.
+
+@example
+router bgp 7675
+ neighbor 192.168.0.1 remote-as 100
+ neighbor 192.168.0.1 route-map RMAP in
+!
+ip community-list 70 permit 7675:70
+ip community-list 70 deny
+ip community-list 80 permit 7675:80
+ip community-list 80 deny
+ip community-list 90 permit 7675:90
+ip community-list 90 deny
+!
+route-map RMAP permit 10
+ match community 70
+ set local-preference 70
+!
+route-map RMAP permit 20
+ match community 80
+ set local-preference 80
+!
+route-map RMAP permit 30
+ match community 90
+ set local-preference 90
+@end example
+
+  Following configuration announce 10.0.0.0/8 from AS 100 to AS 7675.
+The route has communities value 7675:80 so when above configuration
+exists in AS 7675, announced route's local preference will be set to
+value 80.
+
+@example
+router bgp 100
+ network 10.0.0.0/8
+ neighbor 192.168.0.2 remote-as 7675
+ neighbor 192.168.0.2 route-map RMAP out
+!
+ip prefix-list PLIST permit 10.0.0.0/8
+!
+route-map RMAP permit 10
+ match ip address prefix-list PLIST
+ set community 7675:80
+@end example
+
+  Following configuration is an example of BGP route filtering using
+communities attribute.  This configuration only permit BGP routes
+which has BGP communities value 0:80 or 0:90.  Network operator can
+put special internal communities value at BGP border router, then
+limit the BGP routes announcement into the internal network.
+
+@example
+router bgp 7675
+ neighbor 192.168.0.1 remote-as 100
+ neighbor 192.168.0.1 route-map RMAP in
+!
+ip community-list 1 permit 0:80 0:90
+!
+route-map RMAP permit in
+ match community 1
+@end example
+
+  Following exmaple filter BGP routes which has communities value 1:1.
+When there is no match community-list returns deny.  To avoid
+filtering all of routes, we need to define permit any at last.
+
+@example
+router bgp 7675
+ neighbor 192.168.0.1 remote-as 100
+ neighbor 192.168.0.1 route-map RMAP in
+!
+ip community-list standard FILTER deny 1:1
+ip community-list standard FILTER permit
+!
+route-map RMAP permit 10
+ match community FILTER
+@end example
+
+  Communities value keyword @code{internet} has special meanings in
+standard community lists.  In below example @code{internet} act as
+match any.  It matches all of BGP routes even if the route does not
+have communities attribute at all.  So community list @code{INTERNET}
+is same as above example's @code{FILTER}.
+
+@example
+ip community-list standard INTERNET deny 1:1
+ip community-list standard INTERNET permit internet
+@end example
+
+  Following configuration is an example of communities value deletion.
+With this configuration communities value 100:1 and 100:2 is removed
+from BGP updates.  For communities value deletion, only @code{permit}
+community-list is used.  @code{deny} community-list is ignored.
+
+@example
+router bgp 7675
+ neighbor 192.168.0.1 remote-as 100
+ neighbor 192.168.0.1 route-map RMAP in
+!
+ip community-list standard DEL permit 100:1 100:2
+!
+route-map RMAP permit 10

+to provide VPN functionality.  At the same time it requires a new
+framework for policy routing.  With BGP Extended Communities Attribute
+we can use Route Target or Site of Origin for implementing network
+policy for MPLS VPN/BGP.
+
+  BGP Extended Communities Attribute is similar to BGP Communities
+Attribute.  It is an optional transitive attribute.  BGP Extended
+Communities Attribute can carry multiple Extended Community value.
+Each Extended Community value is eight octet length.
+
+  BGP Extended Communities Attribute provides an extended range
+compared with BGP Communities Attribute.  Adding to that there is a
+type field in each value to provides community space structure.
+
+  There are two format to define Extended Community value.  One is AS
+based format the other is IP address based format.
+
+@table @code
+@item AS:VAL
+This is a format to define AS based Extended Community value.
+@code{AS} part is 2 octets Global Administrator subfield in Extended

+This command defines a new standard extcommunity-list.
+@var{extcommunity} is extended communities value.  The

+@section Capability Negotiation
+
+  When adding IPv6 routing information exchange feature to BGP.  There
+were some proposals.  @acronym{IETF} @acronym{IDR} working group finally
+take a proposal called Multiprotocol Extension for BGP.  The
+specification is described in RFC2283.  The protocol does not define new
+protocols.  It defines new attributes to existing BGP.  When it is used
+exchanging IPv6 routing information it is called BGP-4+.  When it is
+used for exchanging multicast routing information it is called MBGP.
+
+  @command{bgpd} supports Multiprotocol Extension for BGP.  So if remote peer
+supports the protocol, @command{bgpd} can exchange IPv6 and/or multicast routing
+information.
+
+  Traditional BGP does not have the feature to detect remote peer's
+capability whether it can handle other than IPv4 unicast routes.  This
+is a big problem using Multiprotocol Extension for BGP to operational
+network.  @cite{draft-ietf-idr-bgp4-cap-neg-04.txt} is proposing a
+feature called Capability Negotiation.  @command{bgpd} use this Capability
+Negotiation to detect remote peer's capabilities.  If the peer is only
+configured as IPv4 unicast neighbor, @command{bgpd} does not send these Capability
+Negotiation packets.
+
+  By default, Zebra will bring up peering with minimal common capability
+for the both sides.  For example, local router has unicast and multicast 
+capabilitie and remote router has unicast capability.  In this case,
+the local router will establish the connection with unicast only capability.
+When there are no common capabilities, Zebra sends Unsupported Capability
+error and then resets the connection.
+
+  If you want to completely match capabilities with remote peer.  Please
+use @command{strict-capability-match} command.
+  
+@deffn {BGP} {neighbor @var{peer} strict-capability-match} {}
+@deffnx {BGP} {no neighbor @var{peer} strict-capability-match} {}
+Strictly compares remote capabilities and local capabilities.  If capabilities
+are different, send Unsupported Capability error then reset connection.
+@end deffn
+
+  You may want to disable sending Capability Negotiation OPEN message
+optional parameter to the peer when remote peer does not implement
+Capability Negotiation.  Please use @command{dont-capability-negotiate}
+command to disable the feature.
+
+@deffn {BGP} {neighbor @var{peer} dont-capability-negotiate} {}
+@deffnx {BGP} {no neighbor @var{peer} dont-capability-negotiate} {}
+Suppress sending Capability Negotiation as OPEN message optional
+parameter to the peer.  This command only affects the peer is configured
+other than IPv4 unicast configuration.
+@end deffn
+
+  When remote peer does not have capability negotiation feature, remote
+peer will not send any capabilities at all.  In that case, bgp configures
+the peer with configured capabilities.
+
+  You may prefer locally configured capabilities more than the negotiated
+capabilities even though remote peer sends capabilities.  If the peer is
+configured by @command{override-capability}, @command{bgpd} ignores received
+capabilities then override negotiated capabilities with configured values.
+
+@deffn {BGP} {neighbor @var{peer} override-capability} {}
+@deffnx {BGP} {no neighbor @var{peer} override-capability} {}
+Override the result of Capability Negotiation with local configuration.
+Ignore remote peer's capability value.

+@section Route Server
+
+At an Internet Exchange point, many ISPs are connected to each other by
+external BGP peering.  Normally these external BGP connection are done by
+@code{full mesh} method.  As with internal BGP full mesh formation,
+this method has a scaling problem.
+
+This scaling problem is well known.  Route Server is a method to resolve
+the problem.  Each ISP's BGP router only peers to Route Server.  Route
+Server serves as BGP information exchange to other BGP routers.  By
+applying this method, numbers of BGP connections is reduced from
+O(n*(n-1)/2) to O(n).
+
+Unlike normal BGP router, Route Server must have several routing tables
+for managing different routing policies for each BGP speaker.  We call the
+routing tables as different @code{view}s.  @command{bgpd} can work as
+normal BGP router or Route Server or both at the same time.

+@node Filtering
+@comment  node-name,  next,  previous,  up
+@chapter Filtering
+
+Zebra provides many very flexible filtering features.  Filtering is used
+for both input and output of the routing information.  Once filtering is
+defined, it can be applied in any direction.
+
+@menu
+* IP Access List::              
+* IP Prefix List::              
+@end menu
+
+@node IP Access List, IP Prefix List, Filtering, Filtering
+@comment  node-name,  next,  previous,  up
+@subsection IP Access List
+
+@deffn {Command} {access-list @var{name} permit @var{ipv4-network}} {}
+@deffnx {Command} {access-list @var{name} deny @var{ipv4-network}} {}
+@end deffn
+
+Basic filtering is done by @code{access-list} as shown in the
+following example.
+
+@example
+access-list filter deny 10.0.0.0/9
+access-list filter permit 10.0.0.0/8
+@end example
+
+@node IP Prefix List,  , IP Access List, Filtering
+@comment  node-name,  next,  previous,  up
+@subsection IP Prefix List
+
+@command{ip prefix-list} provides the most powerful prefix based
+filtering mechanism.  In addition to @command{access-list} functionality,
+@command{ip prefix-list} has prefix length range specification and
+sequential number specification.  You can add or delete prefix based
+filters to arbitrary points of prefix-list using sequential number specification.
+
+If no ip prefix-list is specified, it acts as permit.  If @command{ip prefix-list} 
+is defined, and no match is found, default deny is applied.
+
+@c @deffn {Command} {ip prefix-list @var{name} [seq @var{number}] permit|deny [le @var{prefixlen}] [ge @var{prefixlen}]} {}
+@deffn {Command} {ip prefix-list @var{name} (permit|deny) @var{prefix} [le @var{len}] [ge @var{len}]} {}
+@deffnx {Command} {ip prefix-list @var{name} seq @var{number} (permit|deny) @var{prefix} [le @var{len}] [ge @var{len}]} {}
+
+You can create @command{ip prefix-list} using above commands.
+
+@table @asis
+
+@item @asis{seq}
+seq @var{number} can be set either automatically or manually.  In the
+case that sequential numbers are set manually, the user may pick any
+number less than 4294967295.  In the case that sequential number are set
+automatically, the sequential number will increase by a unit of five (5)
+per list.  If a list with no specified sequential number is created
+after a list with a specified sequential number, the list will
+automatically pick the next multiple of five (5) as the list number.
+For example, if a list with number 2 already exists and a new list with
+no specified number is created, the next list will be numbered 5.  If
+lists 2 and 7 already exist and a new list with no specified number is
+created, the new list will be numbered 10.
+
+@item @asis{le}
+@command{le} command specifies prefix length.  The prefix list will be 
+applied if the prefix length is less than or equal to the le prefix length.
+
+@item @asis{ge}
+@command{ge} command specifies prefix length.  The prefix list will be 
+applied if the prefix length is greater than or equal to the ge prefix length.
+
+@end table
+
+@end deffn
+
+Less than or equal to prefix numbers and greater than or equal to
+prefix numbers can be used together.  The order of the le and ge
+commands does not matter.
+
+If a prefix list with a different sequential number but with the exact
+same rules as a previous list is created, an error will result.
+However, in the case that the sequential number and the rules are
+exactly similar, no error will result.
+
+If a list with the same sequential number as a previous list is created,
+the new list will overwrite the old list.
+
+Matching of IP Prefix is performed from the smaller sequential number to the
+larger.  The matching will stop once any rule has been applied.
+
+In the case of no le or ge command, 
+
+Version 0.85: the matching rule will apply to all prefix lengths that
+matched the prefix list.
+
+Version 0.86 or later: In the case of no le or ge command, the prefix
+length must match exactly the length specified in the prefix list.

+@cindex Options to @code{./configure}
+ 
+  Zebra has an excellent configure script which
+automatically detects most host configurations.  There are several
+additional configure options you can use to turn off IPv6 support, to
+disable the compilation of specific daemons, and to enable SNMP support.
+
+@table @option
+@item --enable-guile
+Turn on compilation of the zebra-guile interpreter.  You will need the
+guile library to make this.  zebra-guile implementation is not yet
+finished.  So this option is only useful for zebra-guile developers.
+@item --disable-ipv6
+Turn off IPv6 related features and daemons.  Zebra configure script
+automatically detects IPv6 stack.  But sometimes you might want to
+disable IPv6 support of Zebra.
+@item --disable-zebra
+Do not build zebra daemon.
+@item --disable-ripd
+Do not build ripd.
+@item --disable-ripngd
+Do not build ripngd.
+@item --disable-ospfd
+Do not build ospfd.
+@item --disable-ospf6d
+Do not build ospf6d.
+@item --disable-bgpd
+Do not build bgpd.
+@item --disable-bgp-announce
+Make @command{bgpd} which does not make bgp announcements at all.  This
+feature is good for using @command{bgpd} as a BGP announcement listener.
+@item --enable-netlink
+Force to enable @sc{gnu}/Linux netlink interface.  Zebra configure
+script detects netlink interface by checking a header file.  When the header
+file does not match to the current running kernel, configure script will
+not turn on netlink support.
+@item --enable-snmp
+Enable SNMP support.  By default, SNMP support is disabled.
+@end table
+
+You may specify any combination of the above options to the configure
+script.  By default, the executables are placed in @file{/usr/local/sbin} 
+and the configuration files in @file{/usr/local/etc}. The @file{/usr/local/}
+installation prefix and other directories may be changed using the following 
+options to the configuration script.
+
+@table @option
+@item --prefix=@var{prefix}
+Install architecture-independent files in @var{prefix} [/usr/local].
+@item --sysconfdir=@var{dir}
+Read-only sample configuration file in @var{dir} [@var{prefix}/etc].
+@end table
+
+@example
+% ./configure --disable-ipv6
+@end example
+
+This command will configure zebra and the routing daemons.
+
+@cindex Configuring Zebra
+@cindex Configuration the software build
+@cindex Building on Linux boxes
+@cindex Linux configurations
+
+There are several options available only to @sc{gnu}/Linux systems:
+@footnote{GNU/Linux has very flexible kernel configuration features.  If
+you use GNU/Linux, make sure that the current kernel configuration is
+what you want.  Zebra will run with any kernel configuration but some
+recommendations do exist.
+
+@table @var
+
+@item CONFIG_NETLINK
+Kernel/User netlink socket.  
+This is a brand new feature which enables
+an advanced interface between the Linux kernel and Zebra (@pxref{Kernel Interface}).
+
+@item CONFIG_RTNETLINK
+Routing messages.
+This makes it possible to receive netlink routing messages.  If you
+specify this option, @command{zebra} can detect routing information
+updates directly from the kernel (@pxref{Kernel Interface}).
+
+@item CONFIG_IP_MULTICAST
+IP: multicasting.  
+This option should be specified when you use @command{ripd} or
+@command{ospfd} because these protocols use multicast.
+
+@end table
+
+IPv6 support has been added in @sc{gnu}/Linux kernel version 2.2.  If you
+try to use the Zebra IPv6 feature on a @sc{gnu}/Linux kernel, please
+make sure the following libraries have been installed.  Please note that

+Zebra fully supports IPv6 routing.  As described so far, Zebra supports
+RIPng, OSPFv3 and BGP-4+.  You can give IPv6 addresses to an interface
+and configure static IPv6 routing information.  Zebra-IPv6 also provides
+automatic address configuration via a feature called @code{address
+auto configuration}.  To do it, the router must send router advertisement
+messages to the all nodes that exist on the network.

+@chapter Kernel Interface
+
+There are several different methods for reading kernel routing table
+information, updating kernel routing tables, and for looking up
+interfaces.
+
+@table @samp
+
+@item ioctl
+The @samp{ioctl} method is a very traditional way for reading or writing
+kernel information.  @samp{ioctl} can be used for looking up interfaces
+and for modifying interface addresses, flags, mtu settings and other
+types of information.  Also, @samp{ioctl} can insert and delete kernel
+routing table entries.  It will soon be available on almost any platform
+which zebra supports, but it is a little bit ugly thus far, so if a
+better method is supported by the kernel, zebra will use that.
+
+@item sysctl
+@samp{sysctl} can lookup kernel information using MIB (Management
+Information Base) syntax.  Normally, it only provides a way of getting
+information from the kernel.  So one would usually want to change kernel
+information using another method such as @samp{ioctl}.
+
+@item proc filesystem
+@samp{proc filesystem} provides an easy way of getting kernel
+information.
+
+@item routing socket
+
+@item netlink
+On recent Linux kernels (2.0.x and 2.2.x), there is a kernel/user
+communication support called @code{netlink}.  It makes asynchronous
+communication between kernel and Zebra possible, similar to a routing
+socket on BSD systems.
+
+Before you use this feature, be sure to select (in kernel configuration) 
+the kernel/netlink support option 'Kernel/User network link driver' and 
+'Routing messages'.
+
+Today, the /dev/route special device file is obsolete.  Netlink
+communication is done by reading/writing over netlink socket.
+
+After the kernel configuration, please reconfigure and rebuild Zebra.
+You can use netlink as a dynamic routing update channel between Zebra
+and the kernel.

+defines static prefix and gateway.
+
+@deffn Command {ip route @var{network} @var{gateway}} {}
+@var{network} is destination prefix with format of A.B.C.D/M.
+@var{gateway} is gateway for the prefix.  When @var{gateway} is
+A.B.C.D format.  It is taken as a IPv4 address gateway.  Otherwise it
+is treated as an interface name.
+
+@example
+ip route 10.0.0.0/8 10.0.0.2
+ip route 10.0.0.0/8 ppp0
+@end example
+
+First example defines 10.0.0.0/8 static route with gateway 10.0.0.2.
+Second one defines the same prefix but with gateway to interface ppp0.
+@end deffn
+
+@deffn Command {ip route @var{network} @var{netmask} @var{gateway}} {}
+This is alternate version of above command.  When @var{network} is
+A.B.C.D format, user must define @var{netmask} value with A.B.C.D
+format.  @var{gateway} is same option as above command
+
+@example
+ip route 10.0.0.0 255.255.255.0 10.0.0.2
+ip route 10.0.0.0 255.255.255.0 ppp0
+@end example
+
+This is a same setting using this statement.
+@end deffn
+
+@deffn Command {ip route @var{network} @var{gateway} @var{distance}} {}
+
+@end deffn
+
+Multiple nexthop static route
+
+@example
+ip route 10.0.0.1/32 10.0.0.2
+ip route 10.0.0.1/32 10.0.0.3
+ip route 10.0.0.1/32 eth0
+@end example
+
+If there is no route to 10.0.0.2 and 10.0.0.3, and interface eth0
+is reachable, then the last route is installed into the kernel.
+
+@example
+zebra> show ip route
+S>  10.0.0.1/32 [1/0] via 10.0.0.2 inactive
+                      via 10.0.0.3 inactive
+  *                   is directly connected, eth0
+@end example
+
+Floating static route
+
+@deffn Command {ipv6 route @var{network} @var{gateway}} {}
+
+@end deffn
+
+@deffn Command {ipv6 route @var{network} @var{gateway} @var{distance}} {}
+
+@end deffn
+
+
+@deffn Command {table @var{tableno}} {}
+Select the primary kernel routing table to be used.  This only works
+for kernels supporting multiple routing tables (like GNU/Linux 2.2.x
+and later).  After setting @var{tableno} with this command, 
+static routes defined after this are added to the specified table.

+
+  Zebra is a routing software package that provides TCP/IP based
+routing services with routing protocols support such as RIPv1, RIPv2,
+RIPng, OSPFv2, OSPFv3, BGP-4, and BGP-4+ (@pxref{Supported RFC}).
+Zebra also supports special BGP Route Reflector and Route Server
+behavior.  In addition to traditional IPv4 routing protocols, Zebra
+also supports IPv6 routing protocols.  With SNMP daemon which supports
+SMUX protocol, Zebra provides routing protocol MIBs (@pxref{SNMP
+Support}).
+
+  Zebra uses an advanced software architecture to provide you with a
+high quality, multi server routing engine.  Zebra has an interactive
+user interface for each routing protocol and supports common client
+commands.  Due to this design, you can add new protocol daemons to Zebra
+easily.  You can use Zebra library as your program's client user
+interface.
+
+  Zebra is an official @sc{gnu} software and distributed under the
+@sc{gnu} General Public License.

+@section About Zebra
+@cindex About Zebra
+
+  Today, TCP/IP networks are covering all of the world.  The Internet
+has been deployed in many countries, companies, and to the home.  When
+you connect to the Internet your packet will pass many routers which
+have TCP/IP routing functionality.
+
+  A system with Zebra installed acts as a dedicated router.  With Zebra,
+your machine exchanges routing information with other routers using
+routing protocols.  Zebra uses this information to update the kernel
+routing table so that the right data goes to the right place.  You can
+dynamically change the configuration and you may view routing table
+information from the Zebra terminal interface.
+
+  Adding to routing protocol support, Zebra can setup interface's flags,
+interface's address, static routes and so on.  If you have a small
+network, or a stub network, or xDSL connection, configuring the Zebra
+routing software is very easy.  The only thing you have to do is to set
+up the interfaces and put a few commands about static routes and/or
+default routes.  If the network is rather large, or if the network
+structure changes frequently, you will want to take advantage of Zebra's
+dynamic routing protocol support for protocols such as RIP, OSPF or BGP.
+Zebra is with you.
+
+  Traditionally, UNIX based router configuration is done by
+@command{ifconfig} and @command{route} commands.  Status of routing
+table is displayed by @command{netstat} utility.  Almost of these
+commands work only if the user has root privileges.  Zebra has a different
+system administration method.  There are two user modes in Zebra.  One is
+normal mode, the other is enable mode.  Normal mode user can only view
+system status, enable mode user can change system configuration.  This
+UNIX account independent feature will be great help to the router
+administrator.
+
+  Currently, Zebra supports common unicast routing protocols.  Multicast
+routing protocols such as BGMP, PIM-SM, PIM-DM will be supported in
+Zebra 2.0.  MPLS support is going on.  In the future, TCP/IP filtering
+control, QoS control, diffserv configuration will be added to Zebra.
+Zebra project's final goal is making a productive, quality free TCP/IP
+routing software.

+@node System Architecture, Supported Platforms, About Zebra, Overview
+@comment  node-name,  next,  previous,  up
+@section System Architecture
+@cindex System architecture
+@cindex Software architecture
+@cindex Software internals
+
+  Traditional routing software is made as a one process program which
+provides all of the routing protocol functionalities.  Zebra takes a
+different approach.  It is made from a collection of several daemons
+that work together to build the routing table.  There may be several
+protocol-specific routing daemons and zebra the kernel routing manager.
+
+  The @command{ripd} daemon handles the RIP protocol, while
+@command{ospfd} is a daemon which supports OSPF version 2.
+@command{bgpd} supports the BGP-4 protocol.  For changing the kernel
+routing table and for redistribution of routes between different routing
+protocols, there is a kernel routing table manager @command{zebra}
+daemon.  It is easy to add a new routing protocol daemons to the entire
+routing system without affecting any other software.  You need to run only
+the protocol daemon associated with routing protocols in use.  Thus,
+user may run a specific daemon and send routing reports to a central
+routing console.
+
+  There is no need for these daemons to be running on the same machine.
+You can even run several same protocol daemons on the same machine.  This
+architecture creates new possibilities for the routing system.
+
+@example
+@group
++----+  +----+  +-----+  +-----+
+|bgpd|  |ripd|  |ospfd|  |zebra|
++----+  +----+  +-----+  +-----+
+                            |
++---------------------------|--+
+|                           v  |
+|  UNIX Kernel  routing table  |
+|                              |
++------------------------------+
+
+    Zebra System Architecture
+@end group
+@end example
+
+  Multi-process architecture brings extensibility, modularity and
+maintainability.  At the same time it also brings many configuration
+files and terminal interfaces.  Each daemon has it's own configuration
+file and terminal interface.  When you configure a static route, it must
+be done in @command{zebra} configuration file.  When you configure BGP
+network it must be done in @command{bgpd} configuration file.  This can be a
+very annoying thing.  To resolve the problem, Zebra provides integrated
+user interface shell called @command{vtysh}.  @command{vtysh} connects to
+each daemon with UNIX domain socket and then works as a proxy for user input.
+
+  Zebra was planned to use multi-threaded mechanism when it runs with a
+kernel that supports multi-threads.  But at the moment, the thread
+library which comes with @sc{gnu}/Linux or FreeBSD has some problems with
+running reliable services such as routing software, so we don't use
+threads at all.  Instead we use the @command{select(2)} system call for
+multiplexing the events.
+
+  When @command{zebra} runs under a @sc{gnu} Hurd kernel it will act as a
+kernel routing table itself.  Under @sc{gnu} Hurd, all TCP/IP services are
+provided by user processes called @command{pfinet}.  Zebra will provide
+all the routing selection mechanisms for the process.  This feature will
+be implemented when @sc{gnu} Hurd becomes stable.

+
+RIP -- Routing Information Protocol is widely deployed interior gateway
+protocol.  RIP was developed in the 1970s at Xerox Labs as part of the
+XNS routing protocol.  RIP is a @dfn{distance-vector} protocol and is
+based on the @dfn{Bellman-Ford} algorithms.  As a distance-vector
+protocol, RIP router send updates to its neighbors periodically, thus
+allowing the convergence to a known topology.  In each update, the
+distance to any given network will be broadcasted to its neighboring
+router.
+
+@command{ripd} supports RIP version 2 as described in RFC2453 and RIP
+version 1 as described in RFC1058.

+@section Starting and Stopping ripd
+
+The default configuration file name of @command{ripd}'s is
+@file{ripd.conf}.  When invocation @command{ripd} searches directory
+@value{INSTALL_PREFIX_ETC}.  If @file{ripd.conf} is not there next
+search current directory.
+
+RIP uses UDP port 521 to send and receive RIP packets.  So the user must have
+the capability to bind the port, generally this means that the user must
+have superuser privileges.  RIP protocol requires interface information
+maintained by @command{zebra} daemon.  So running @command{zebra}
+is mandatory to run @command{ripd}.  Thus minimum sequence for running
+RIP is like below:
+
+@example
+@group
+# zebra -d
+# ripd -d
+@end group
+@end example
+
+Please note that @command{zebra} must be invoked before @command{ripd}.
+
+To stop @command{ripd}.  Please use @command{kill `cat
+/var/run/ripd.pid`}.  Certain signals have special meaningss to @command{ripd}.
+
+@table @samp
+@item SIGHUP
+Reload configuration file @file{ripd.conf}.  All configurations are

+@subsection RIP netmask
+
+The netmask features of @command{ripd} support both version 1 and version 2 of
+RIP.  Version 1 of RIP originally contained no netmask information.  In
+RIP version 1, network classes were originally used to determine the
+size of the netmask.  Class A networks use 8 bits of mask, Class B
+networks use 16 bits of masks, while Class C networks use 24 bits of
+mask.  Today, the most widely used method of a network mask is assigned
+to the packet on the basis of the interface that received the packet.
+Version 2 of RIP supports a variable length subnet mask (VLSM).  By
+extending the subnet mask, the mask can be divided and reused.  Each
+subnet can be used for different purposes such as large to middle size
+LANs and WAN links.  Zebra @command{ripd} does not support the non-sequential
+netmasks that are included in RIP Version 2.
+
+In a case of similar information with the same prefix and metric, the
+old information will be suppressed.  Ripd does not currently support
+equal cost multipath routing.

+@section RIP Configuration
+
+@deffn Command {router rip} {}
+The @code{router rip} command is necessary to enable RIP.  To disable
+RIP, use the @code{no router rip} command.  RIP must be enabled before
+carrying out any of the RIP commands.
+@end deffn
+
+@deffn Command {no rouer rip} {}
+Disable RIP.
+@end deffn
+
+RIP can be configured to process either Version 1 or Version 2 packets,
+the default mode is Version 2.  If no version is specified, then the RIP
+daemon will default to Version 2.  If RIP is set to Version
+1, the setting "Version 1" will be displayed, but the setting "Version
+2" will not be displayed whether or not Version 2 is set explicitly as
+the version of RIP being used.
+
+@deffn {RIP Command} {network @var{network}} {}
+@deffnx {RIP Command} {no network @var{network}} {}
+Set the RIP enable interface by @var{network}.  The interfaces which
+have addresses matching with @var{network} are enabled.
+
+This group of commands either enables or disables RIP interfaces between
+certain numbers of a specified network address.  For example, if the
+network for 10.0.0.0/24 is RIP enabled, this would result in all the
+addresses from 10.0.0.0 to 10.0.0.255 being enabled for RIP.  The @code{no
+network} command will disable RIP for the specified network.
+@end deffn
+
+@deffn {RIP Command} {network @var{ifname}} {}
+@deffnx {RIP Command} {no network @var{ifname}} {}
+Set a RIP enabled interface by @var{ifname}.  Both the sending and
+receiving of RIP packets will be enabled on the port specified in the
+@code{network ifname} command.  The @code{no network ifname} command will disable
+RIP on the specified interface.
+@end deffn
+
+@deffn {RIP Command} {neighbor @var{a.b.c.d}} {}
+@deffnx {RIP Command} {no neighbor @var{a.b.c.d}} {}
+Specify RIP neighbor.  When a neighbor doesn't understand multicast,
+this command is used to specify neighbors.  In some cases, not all
+routers will be able to understand multicasting, where packets are sent
+to a network or a group of addresses.  In a situation where a neighbor
+cannot process multicast packets, it is necessary to establish a direct
+link between routers.  The neighbor command allows the network
+administrator to specify a router as a RIP neighbor.  The @code{no
+neighbor a.b.c.d} command will disable the RIP neighbor.
+@end deffn
+
+Below is very simple RIP configuration.  Interface @code{eth0} and
+interface which address match to @code{10.0.0.0/8} are RIP enabled.
+
+@example
+@group
+!
+router rip
+ network 10.0.0.0/8
+ network eth0
+!
+@end group
+@end example
+
+Passive interface
+
+@deffn {RIP command} {passive-interface @var{IFNAME}} {}
+@deffnx {RIP command} {no passive-interface @var{IFNAME}} {}
+This command sets the specified interface to passive mode.  On passive mode
+interface, all receiving packets are processed as normal and ripd does
+not send either multicast or unicast RIP packets except to RIP neighbors
+specified with @code{neighbor} command.
+@end deffn
+
+RIP version handling
+
+@deffn {RIP Command} {version @var{version}} {}
+Set RIP process's version.  @var{version} can be ``1'' or ``2''.
+@end deffn
+
+@deffn {Interface command} {ip rip send version @var{version}} {}
+@var{version} can be `1', `2', `1 2'.  This configuration command
+overrides the router's rip version setting.  The command will enable the
+selected interface to send packets with RIP Version 1, RIP Version 2, or
+both.  In the case of '1 2', packets will be both broadcast and
+multicast.
+@end deffn
+
+@deffn {Interface command} {ip rip receive version @var{version}} {}
+Version setting for incoming RIP packets.  This command will enable the
+selected interface to receive packets in RIP Version 1, RIP Version 2,
+or both.
+@end deffn
+
+RIP split-horizon
+
+@deffn {Interface command} {ip split-horizon} {}
+@deffnx {Interface command} {no ip split-horizon} {}
+Control split-horizon on the interface.  Default is @code{ip

+@section RIP route-map
+
+Usage of @command{ripd}'s route-map support.
+
+Optional argument route-map MAP_NAME can be added to each @code{redistribute}
+statement.
+
+@example
+redistribute static [route-map MAP_NAME]
+redistribute connected [route-map MAP_NAME]
+.....
+@end example
+
+Cisco applies route-map _before_ routes will exported to rip route
+table.  In current Zebra's test implementation, @command{ripd} applies route-map
+after routes are listed in the route table and before routes will be announced
+to an interface (something like output filter). I think it is not so clear,
+but it is draft and it may be changed at future.
+
+Route-map statement (@pxref{Route Map}) is needed to use route-map
+functionality.
+
+@deffn {Route Map} {match interface @var{word}} {}
+This command match to incoming interface.  Notation of this match is
+different from Cisco. Cisco uses a list of interfaces - NAME1 NAME2
+... NAMEN.  Ripd allows only one name (maybe will change in the
+future).  Next - Cisco means interface which includes next-hop of
+routes (it is somewhat similar to "ip next-hop" statement).  Ripd
+means interface where this route will be sent. This difference is
+because "next-hop" of same routes which sends to different interfaces
+must be different. Maybe it'd be better to made new matches - say
+"match interface-out NAME" or something like that.
+@end deffn
+
+@deffn {Route Map} {match ip address @var{word}} {}
+@deffnx {Route Map} {match ip address prefix-list @var{word}} {}
+Match if route destination is permitted by access-list.
+@end deffn
+
+@deffn {Route Map} {match ip next-hop A.B.C.D} {}
+Cisco uses here <access-list>, @command{ripd} IPv4 address. Match if
+route has this next-hop (meaning next-hop listed in the rip route
+table - "show ip rip")
+@end deffn
+
+@deffn {Route Map} {match metric <0-4294967295>} {}
+This command match to the metric value of RIP updates.  For other
+protocol compatibility metric range is shown as <0-4294967295>.  But
+for RIP protocol only the value range <0-16> make sense.
+@end deffn
+
+@deffn {Route Map} {set ip next-hop A.B.C.D} {}
+This command set next hop value in RIPv2 protocol.  This command does
+not affect RIPv1 because there is no next hop field in the packet.
+@end deffn
+
+@deffn {Route Map} {set metric <0-4294967295>} {}
+Set a metric for matched route when sending announcement.  The metric
+value range is very large for compatibility with other protocols.  For
+RIP, valid metric values are from 1 to 16.

+The default settings for the timers are as follows:

+The update timer is 30 seconds. Every update timer seconds, the RIP
+process is awakened to send an unsolicited Response message containing
+the complete routing table to all neighboring RIP routers.

+The timeout timer is 180 seconds. Upon expiration of the timeout, the
+route is no longer valid; however, it is retained in the routing table
+for a short time so that neighbors can be notified that the route has
+been dropped.

+
+SNMP (Simple Network Managing Protocol) is widely implemented feature
+for collecting network information from router and/or host.  Zebra
+itself does not support SNMP agent functionality.  But conjuction with
+SNMP agent, Zebra provides routing protocol MIBs.
+
+Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
+agent.  There are several SNMP agent which support SMUX.  We recommend
+to use the latest @command{ucd-snmp} software.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+%
+% For those who want to use more than one line's worth of words in
+% the preamble, break the line within one argument and it
+% will parse correctly, i.e.,
+%
+%     @multitable {Column 1 template} {Column 2 template} {Column 3
+%      template}
+% Not:
+%     @multitable {Column 1 template} {Column 2 template}
+%      {Column 3 template}
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab, @multitable or @end multitable do not need to be on their
+% own lines, but it will not hurt if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.
+%   0pt means it depends on current normal line spacing.

+@command{vtysh} is integrated shell of Zebra software.
+
+To use vtysh please specify ---enable-vtysh to configure script.  To use
+PAM for authentication use ---with-libpam option to configure script.
+
+vtysh only searches @value{INSTALL_PREFIX_ETC} path for vtysh.conf which
+is the vtysh configuration file.  Vtysh does not search current
+directory for configuration file because the file includes user
+authentication settings.
+
+Currently, vtysh.conf has only one command.
+
+@example
+!
+username foo nopassword
+!
+@end example
+
+With this set, user foo does not need password authentication for user vtysh.
+With PAM vtysh uses PAM authentication mechanism.
+
+If vtysh is compiled without PAM authentication, every user can use vtysh
+without authentication.
