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

: Routing policy name, a case-sensitive string of 1 to 63 characters.

half-life-reachable, half-life-unreachable, reuse, suppres

s and

ceiling

are mutually dependent. Once

any one is configured, all the others should also be specified.

Description

Use

dampening

to enable BGP route dampening, configure dampening parameters, or both.

Use

undo dampening

to disable route dampening.

By default, no route dampening is configured.

The command dampens only EBGP routes rather than IBGP routes.
