Parameters
half-life-reachable: Specifies a half-life for active routes from 1 to 45 minutes. By default, the value is 15
minutes.
half-life-unreachable: Specifies a half-life for suppressed routes from 1 to 45 minutes. By default, the
value is 15 minutes.
reuse: Specifies a reuse threshold value for suppressed routes from 1 to 20000. A suppressed route
whose penalty value decreases under the value is reused. By default, the reuse value is 750.
suppress: Specifies a suppression threshold from 1 to 20000. The route with a penalty value higher than
the threshold is suppressed. The default value 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: Specifies routing policy name, a case-sensitive string of 1 to 63 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.
Usage guidelines
The command dampens only EBGP routes rather than IBGP routes.
