BMP

Overview

BMP is a protocol used for monitoring BGP sessions. BMP allows a BGP router (BMP client) to advertise unprocessed routing information it has received from its peers to a monitoring station. The peer can be configured to send pre policy route information, post policy information, or both. The monitoring station can then monitor routing table size, identify issues and monitor trends in table size and update and withdraw frequency.

A BMP client is configured to create monitoring sessions using TCP with one or more monitoring stations.

The following are some of the messages provided by BMP during a monitoring session:

• Route Monitoring: the initial dump of all routes received from a peer and ongoing updates to the list of paths advertised by a peer

• Statistics Reports: output of statistics sent periodically to the monitoring station

• Peer Up Notification: sent whenever a peering session is established

• Peer Down Notification: sent whenever a peering session is terminated, including reasons for termination
