Route dampening is a mechanism used to minimize the instability caused by route flapping and oscillation over the network. The following is the command used to control route dampening:
bgp dampening [[route-map map-name] [half-life-time reuse-value suppress-value maximum-suppress-time]]
half-life-time is in the range of 1 to 45 minutes. The current default is 15 minutes.
reuse-value is in the range of 1 to 20000. The default is 750.
suppress-value is in the range of 1 to 20000. The default is 2000.
maximum-suppress-time is the maximum duration that a route can be suppressed. The range is 1 to 255. The default is 4 × half-life-time.
A route map can be associated with BGP dampening to selectively apply the dampening ...
