7.8.1.0 Introduced on the S-Series.
7.7.1.0 Introduced on the C-Series.
Usage
Information
At least one of the routes included in the aggregate address must be in the BGP routing table for the
configured aggregate to become active.
If routes within the aggregate are constantly changing, do not add the as-set parameter to the
aggregate as the aggregate flaps to keep track of the changes in the AS_PATH.
In route maps used in the suppress-map parameter, routes meeting the deny clause are not suppress;
in other words, they are allowed. The opposite is also true; routes meeting the permit clause are
suppressed.
If the route is injected via the network command, that route still appears in the routing table if the
summary-only parameter is configured in the aggregate-address command.
The summary-only parameter suppresses all advertisements. If you want to suppress advertisements
to only specific neighbors, use the neighbor distribute-list command.
bgp dampening
Enable MBGP route dampening.
Syntax
bgp dampening [half-life time] [route-map map-name]
To disable route dampening, use the no bgp dampening [half-life time] [route-map map-
name] command.
Parameters
half-life time (OPTIONAL) Enter the number of minutes after which the Penalty is decreased.
