What is BGP maximum prefix?
Prefix Limits and BGP Peering Sessions Use the neighbor maximum-prefix command to limit the maximum number of prefixes that a device running BGP can receive from a peer. When the device receives too many prefixes from a peer and the maximum-prefix limit is exceeded, the peering session is disabled or brought down.
What is Route dampening in BGP?
Route Dampening is a way to suppress flapping routes so that they are “suppressed” instead of being advertised. An unstable network can cause BGP routes to flap, which can cause other BGP routers in the network to constantly reconverge. This wastes valuable CPU cycles and can cause severe problems in the network.
