By default, no confederation peer sub-ASs are configured.
Before this configuration, the
confederation id
command must be used to specify the confederation
for the sub-ASs.
If the
undo confederation peer-as
command without the
as-number-list
argument is used, all
confederation peer sub-ASs are removed.

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
: Routing policy name, a string of 1 to 19 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 accordingly.
Description
Use the
dampening
command to enable BGP route dampening and/or configure dampening
parameters.
Use the
undo dampening
command to disable route dampening.
