Cisco Cisco IOS Software Release 12.2(33)SRE

The BGP Support for Fast Peering Session Deactivation feature introduces an event-driven notification 
system that allows a Border Gateway Protocol (BGP) process to monitor BGP peering sessions on a 
per-neighbor basis. This feature improves the response time of BGP to adjacency changes by allowing 
BGP to detect an adjacency change and deactivate the terminated session in between standard BGP 
scanning intervals. Enabling this feature improves overall BGP convergence.

Configuration information is included in the “Configuring BGP Neighbor Session Options” chapter of
