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.
