3. 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.

5. What benefit of BMP(BGP Monitoring Protocol)
 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.

6. 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
