The April 5, 2002 version of bgp.monitor currently on the Mon contrib site does not seem to properly display the IP address of the remote peer when there is an error condition. At least that's the case for me right now, with a Cisco 7513 running IOS 12.0.23s. Here is a patch that corrects the problem, by displaying bgpPeerRemoteAddr rather than bgpPeerIdentifier. Comments welcome, since I'm not all that familiar with this MIB. It seems that bgpPerIdentifier is set to 0.0.0.0 in my Cisco's MIB when the session goes down, which is not all that useful in a Mon alarm.
