Route Dampening

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 ...
