What is BMP
BGP Monitoring Protocol http://tools.ietf.org/html/draft-ietf-grow-bmp
It can monitor BGP Adj-RIBs-In Adj-RIBs-In is unprocessed routing information from
BGP peer. BMP is focused on monitoring of BGP
status/routes/events.

BMP reaches Adj-RIBs-in , operator can check consistency of policy(like a route-map) .
BMP would be easier than today’s BGP monitoring system(screen-scraping approach)
can find reason of disconnection from peer down message.
can know capability/negotiate hold down time of BGP peer from peer up message.
It would be unified UI without any “show” and “debug” on various vendors.

BMP Message
Type Description detail
0 Route Monitoring used for initial synchronization of Adj-RIBs-In
1 Statistics Report monitoring station to observe interesting events that occur on the router
2 Peer Down Notification indicates BGP peering session was terminated. The message includes reason code from BGP notification message
3 Peer Up Notification indicates that a peering session has come up. The message includes remote/local port and open message.
4 Initiation Message inform the monitoring station of its vendor, software version, and so on
5 Termination Message indicate why it is terminating a session
