BGP Support for Fast Peering Session Deactivation
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" module of the Cisco IOS BGP Configuration Guide, Release 12.4T, at the following URL:
