The number of BGP speakers each BGP peer must maintain increases exponentially. Network
management quickly becomes impossible.
Sessions and Peers
When two routers communicate using the BGP protocol, a BGP session is started. The two end-points of
that session are Peers. A Peer is also called a Neighbor.
Establishing a session
Information exchange between peers is driven by events and timers. The focus in BGP is on the traffic
routing policies.
