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.

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.
