[nsp] 7304 IS-IS get stuck after a certain time

[Cor van Rij]

Hi,

we have a 7304 (with dial NSE-100) in the network that is continuously
causing problems. The router is running 12.2(11) YZ1 and is functioning as
edge LSR. After a certain amount of time we see that the IS-IS adjacencies
get lost and BGP peers goes down. According to the cisco the initial issue
was due to the fact that the 7304 had a hardware limitation and the MTU on
both GEs needed to be the same. Last Friday this was fixed in the config but
after 36 hours IS-IS got stuck again.

A search on CCO revelaed no open bugs. Does any one have experience with the
7304, did anyone observe this behaviour on a 7304?

Any pointers would be appreciated!!

regards

cor
