How do I log/monitor my BGP neighbor's FSM states?
If I do a "show bgp neighbor x.x.x.x", I can see the FSM state (up since, down since, etc), but a change in states doesn't make it to the logs - or at least not by default.
I just found out that that's somewhat important for me to know - we lost one of our provider's Internet connection, but the port was still up, and other than the "zero traffic" there was no indication that they were down - and of course the FSM state from "sh bgp neigh".
It would be great if I could log those (for "documentation reasons", i.e. leverage in talks with the providers), and awesome if I could SNMP query them or send traps for monitoring.
Thanks for all the help!
