The command is used to configure multiple adjacent Autonomous Systems in a
confederation. The Autonomous Systems, specified in this command, are visible
internally to the confederation. Each Autonomous System is fully meshed within itself
or configures a route reflector.
Use the no bgp confederation peers command to delete all the or part of the AS
numbers, configured earlier.
Use the show ip bgp confederation command to verify your settings.
In the following example, Autonomous Systems 21, 22, 23, 24, and 25 are
configured to belong to a single confederation using the identifier 10.
This example shows how to delete part of the AS numbers, configured earlier.
Specifies the time, in minutes, after which the penalty of the reachable routes will be
down, by half.
If the penalty for a flapping route decreases enough to fall below this value, the route
is unsuppressed.
A route is suppressed when its penalty exceeds this limit.
Specifies the maximum time, in minutes, that a route can be suppressed.
Specifies the time, in minutes, after which the penalty of the unreachable route will
be down, by half.
Specifies the route map name for configuring the dampening running configuration.
The maximum length is 16 characters.
BGP dampening is disabled by default. The following values are used when this
