Hi,

When that one link goes down, does 'show interface' indicate that the link is down ?

hi Iqbal

The full router config from both the routers and the ip address which you are trying to ping will be useful to identify the problem.

I'm experiencing a similar issue with a 7200 chassis. It worked before the router crashed and reloaded. Was there ever any resolution to this? I realize it was some time ago....
