From fd884852db05e35da9eac6ff67fbaa0736d821c6 Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Fri, 7 Aug 2009 10:48:12 +0000 Subject: zebra, lib: Add ZEBRA_INTERFACE_UNNUMBERED interface flag. Use interface "unnumbered" command to set unnumbered mode. "no unnumbered" will clear it. Changed to use *_FLAG macros by David Lamparter.
