Parameters half-life-reachable: Specifies the half-life for active routes, in the range 1 to 45 minutes. By default, the value is 15 minutes.

half-life-unreachable: Specifies the half-life for active routes, in the range 1 to 45 minutes. By default, the value is 15 minutes.

reuse: Specifies the reuse threshold value for suppressed routes, in the range 1 to 20000. Penalty value of a suppressed route decreasing under the value is reused. By default, its value is 750.

suppress: Specifies a suppression threshold from 1 to 20000, which should be bigger than the reuse value. Routes with a penalty value bigger than the threshold are suppressed. By default, it is 2000.

ceiling: Specifies a ceiling penalty value from 1001 to 20000. The value must be bigger than the suppress value. By default, the value is 16000.

route-policy-name: Routing policy name, a string of 1 to 19 characters.

half-life-reachable, half-life-unreachable, reuse, suppress and ceiling are mutually dependent. Once any one is configured, all the others should also be specified accordingly.

Description Use the dampening command to enable IPv6 BGP route dampening or/and configure dampening parameters.

Use the undo dampening command to disable route dampening.

By default, no route dampening is configured.
