BGP Selective Address Tracking

BGP Selective Address Tracking

The BGP Selective Address Tracking feature introduces the use of a route map for next hop route filtering and fast session deactivation. Selective next hop filtering uses a route map to selectively define routes to help resolve the BGP next-hop and a route map can be used to determine if a peering session with a BGP neighbor should be reset when a route to the BGP peer changes.
