What do you use to monitor routing table changes?

kevin.hu · ‎12-24-2009

I know Cisco sells Route Monitor 2.3 to monitor unicast and multicast routing table changes. However, this product is EOL and EOS. What other products do you use to monitor routing table changes?

Thanks.

"debug ip routing" comes to mind.

Hi Kevin,

You can configure the route profiling feature: 'ip route profile'; it will yield a result that looks like this:

show ip route profile

Thanks for the reply. However, I am looking for a management tool. Let's say I have 3000 routers. This two commands are good for a few routers but not feasible for a lot of routers. I am looking for a management tool that provides a overall routing table health.

Anyone else knows any tool that monistors routing table changes?

Thanks.

Try asking in the network management forum.
