BGP:Fast Peering Session Deactivation

Trackback

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.

Restrictions for BGP Support for Fast Peering Session Deactivation

•This feature is not supported under the IPv6 address family.

•A host route must be available for each peering session that is configured to use BGP fast session deactivation. If a route is aggregated or is an unreachable non-host route (through a loopback interface) but still available to the peer, this feature will not be able to track the route and will be unable to close the session.
