* isisd: add a slight delay to lsp_regenerate_scheduleChristian Franke2015-12-081-0/+37
| | | | | | | | | | | | | | | | | | | | | | | isisd implements a holdoff interval and will refrain from regenerating an lsp if the difference between the current time and its last refresh is less than the holdoff interval. Instead, it will schedule a timer to regenerate the lsp after the holdoff interval has passed. This implementation has one disadvantage in the case where there is a succession of calls to lsp_regenerate_schedule. In such a case, the first call will trigger an immediate regeneration of the lsp, while the other calls will only schedule the regeneration timer. This leads to cases where it takes holdoff interval time for information to propagate, just because the information was only available e.g. at the second call of lsp_regenerate_schedule in such a succession of calls. By not immediately regenerating an lsp if the last generation time is sufficiently long ago, but instead scheduling the regeneration with a very small delay, we allow all information from such a succession of calls to be considered.

* isisd: Attached-bit in LSP headerAmritha Nambiar2015-09-031-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | Set/reset attached-bit in LSP header: This patch provides support for set/reset attached_bit in the LSP header. In IS-IS networks, routing inter-area traffic from L1 areas is accomplished by sending the traffic to the nearest L1/L2 router. A L1/L2 router identifies itself by setting an attach-bit (ATT-bit) in its (LSP). The ATT-bit in LSP can be changed using the set-attached-bit or no-set-attached-bit commands (similar to ‘set-overload-bit’ and 'no set-overload-bit’) using telnet terminal in router configuration mode. Steps: enable configure terminal router isis <Routing area> set-attached-bit V2: Removed looping through area list as this well set the bit for all areas in the list. This implementation now looks exactly like the current overload bit implementation. Signed-off-by: Amritha Nambiar <amritha.nambiar@intel.com>
* *: remove stray extra semicolonsDavid Lamparter2015-04-211-4/+4

* *: use long long to print time_tDavid Lamparter2015-04-191-2/+2
| | | | | | | | | | | | Since we can't assume time_t to be long, int, or even long long, this consistently uses %lld/long long (or %llu/unsigned long long in a few cases) to print time_t/susecond_t values. This should fix a bunch of warnings, on NetBSD in particular. (Unfortunately, there seems to be no "PRId64" style printing macro for time_t...)

* isisd: verify metrics on metric-style transitionChristian Franke2012-12-121-8/+11
| | | | | | | | When switching to metric-style transition, circuit metrics should also be verified to be in the narrow range 0..63. Signed-off-by: Christian Franke <chris@opensourcerouting.org> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* isisd: fix metrics check for metric-style narrowChristian Franke2012-12-121-2/+2
| | | | | | | | | | When switching to narrow metric style, all configured circuits are verified to have a valid narrow style metric. Check te_metric instead of metric_default as the latter is only 8bit wide and may overflow for wide style metrics.

* isisd: save metric-style narrowChristian Franke2012-12-121-0/+5
| | | | | | | | | isisd defaults to wide metric style. So if narrow metric style is configured, a matching setting should be written to the configuration, allowing a narrow metric-style setting to be saved.

Merging L1 and L2 tables in case of L1L2 area. In short - many changes to make SPF work more correctly, add/remove to/from RIB also works now. It's still very far from perfect though.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * (global): Fix up list loops to match changes in lib/linklist, and some basic auditing of usage. * configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES * HACKING: Add notes about deprecating interfaces and commands. * lib/linklist.h: Add usage comments. Rename getdata macro to listgetdata. Rename nextnode to listnextnode and fix its odd behaviour to be less dangerous. Make listgetdata macro assert node is not null, NULL list entries should be bug condition. ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use with for loop, Suggested by Jim Carlson of Sun. Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the "safety" of previous macro. LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to distinguish from the similarly named functions, and reflect their effect better. Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section with the old defines which were modified above, for backwards compatibility - guarded to prevent Quagga using it.. * lib/linklist.c: fix up for linklist.h changes. * ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single scan of the area list, rather than scanning all areas first for INTER_ROUTER and then again for INTER_NETWORK. According to 16.2, the scan should be area specific anyway, and further ospf6d does not seem to implement 16.3 anyway.
