Cisco Router - log BGP changes

I've got a Cisco router that tunnels an IP block over 2 ISP (cable provider and T1 from telco)connections on a failover.  If the cable link goes down, the IP block re-routes over the T1 link.

I'd like to get some sort of log/notification of these events to better track these cutovers.  There are several router-router VPN's that re-key themselves, and I'd like to see if it corresponds to the ISP link re-homing when the cable link "blips".

Thanks for the links.  Dumb question: where does it "log" the changes?  Does it go with other syslog messages and do I need to configure syslog and run an off-router syslog server to capture those neighbor changes?

Thanks.

local logging is limited and will drop old logs so it doesn't overflow available memory.

it would show up as a syslog message, I am not sure what level but informational should include it.

I would set up an external syslog server and point your router at it for all syslog output and see what kind of volume it creates. You can tune what gets sent after you determine what level of data you need.

hope this helps,
