I'm trying to figure out how I can monitor with BGP peer went down using SNMP traps or any other methods that are out there. Basically I would like to get a trap that tells me the IP address of the peer that went down.
Looking over the SNMP MIBs for BGP all i can find is snmp traps that tell me there was a change in states in BGP, but don't say which neighbor.
Is there any way to get such information? Would I have to use EEM with some script? This seems like a very common thing that people would want to know.
Thank you in advance,
