Version 7.8.1.0 Version 7.7.1.0 Introduced support on S-Series Introduced support on C-Series Added support for 4-byte format bgp dampening c e s Enable BGP route dampening and configure the dampening parameters. Syntax Parameters Defaults Command Modes Usage Information bgp dampening [half-life reuse suppress max-suppress-time] [route-map map-name] To disable route dampening, use the no bgp dampening [half-life reuse suppress max-suppress-time] [route-map map-name] command. half-life reuse suppress max-suppress-time route-map map-name (OPTIONAL) Enter the number of minutes after which the Penalty is decreased. After the router assigns a Penalty of 1024 to a route, the Penalty is decreased by half after the half-life period expires. Range: 1 to 45. Default: 15 minutes (OPTIONAL) Enter a number as the reuse value, which is compared to the flapping route's Penalty value. If the Penalty value is less than the reuse value, the flapping route is once again advertised (or no longer suppressed). Range: 1 to 20000. Default: 750 (OPTIONAL) Enter a number as the suppress value, which is compared to the flapping route's Penalty value. If the Penalty value is greater than the suppress value, the flapping route is no longer advertised (that is, it is suppressed). Range: 1 to 20000. Default: 2000 (OPTIONAL) Enter the maximum number of minutes a route can be suppressed. The default is four times the half-life value. Range: 1 to 255. Default: 60 minutes. (OPTIONAL) Enter the keyword route-map followed by the name of a configured route map. Only match commands in the configured route map are supported. Disabled. ROUTER-BGP-ADDRESS FAMILY If you enter bgp dampening, the default values for half-life, reuse, suppress, and max-suppress-time are applied. The parameters are position-dependent, therefore, if you configure one parameter, you must configure the parameters in the order they appear in the CLI. Border Gateway Protocol IPv4 (BGPv4) | 317
