There is also a command under the BRI interface that can be used instead of
the route-map or distribute list between the other protocol and OSPF:
conf t
int bri0/0
no peer neighbor-route
This will take out from the routing table the /32 route pointing to the
other side of the ISDN link. It is this /32 going in and out of the table
that causes the other protocol to alert the OSPF process that there has
been a topology change.
I've seen this route flapping issue on demand-circuits and OSPF on 11.X
IOS versions, but right now I have 12.0(6) and 12.0(7)T, and I'm not seeing
the flapping issue ...
I think someone mentioned this is not a problem in 12.0 in a previous posting?
Regards,
Josi
