Track Routing Nexthop

[CSCO12099251]

Hi All,

I have a simple query. Is there any way we can check the routing changes (I mean the forwarding path changes) which happened in past in router logs?

I am aware sh log can help to display peer changes up/down. Is there any way to track which nexthop was used to forward traffic at a particular time?

Hi  unless you have it setup first  and your collecting teh routing table outputs or specific routes info  , you could do it through EEM and have it collect routing tables every 30 minutes dump them to flash in txt file as one method
