From aa5cf24b9de96245f2166ef1c4e9612890ced1b3 Mon Sep 17 00:00:00 2001 From: David Lamparter Date: Thu, 19 Jul 2012 16:11:50 +0200 Subject: lib: make IPv6 prefix parser slightly more strict This makes it possible to have both "show babel route A.B.C.D/M" and "show babel route X:X::X:X/M" commands at the same time without the parser complaining about ambiguity. * lib/command.c: only accept STATE_DOT after : was seen.
