Hi Chris
For what it's worth, I just yesterday had the situation where IOS (I
think a late 12.4) stopped sending RIP updates out an interface (other
interfaces on the same router still sent RIP fine) even when that
interface was correctly configured for it. In my particular case,
shutting down the interface and bringing it back up "enabled" the
sending of RIP updates out it again. Don't want to sound like a Windows
admin, but you might (if you haven't already) like to try this...or a
reboot... :-) Haven't looked through the Bug Toolkit about this yet.
Regards, Mark.
