bgp dampening
This command is used to configure the route dampening function. Use the
no
form of the command to
restore the default setting.
bgp dampening [HALF-LIFE REUSE SUPPRESS MAX-SUPPRESS-TIME UN-REACHABILTY-
HALF-TIME | route-map MAP-NAME]
no bgp dampening [route-map]
Parameters
HALF-LIFE
(Optional) Specifies the time (in minutes) after which the accumulated
penalty of the route is decreased by half. The range of the half-life
period is 1 to 45 minutes.
REUSE
(Optional) Specifies the penalty that is decreased and falls below the
reuse threshold, the route will be re-entered the routing table as a
normal route. The range of the reuse value is from 1 to 20000.
SUPPRESS
(Optional) Specifies the penalty that is increased and cross the
suppress threshold, the route will become a dampening route and will
not be advertised. The range is from 1 to 20000
MAX-SUPPRESS-TIME
(Optional) Specifies the maximum time (in minutes) that a route can be
in the dampened state. The range is from 1 to 255. The default is 4
times the half-life.
UN-REACHABILITY-HALF-
LIFE
Specifies the time (in minutes) after which the penalty of the
unreachable routes will be down; by half.
route-map MAP-NAME
(Optional) Specifies the name of route map to control the routes for
dampening.
Default
Half–life: 15 minutes.
Reuse: 750.
Suppress: 2000.
Max-suppress-time: 4 times half-life.
Un-reachability-half-life: 15 minutes.
Command Mode
Router Configuration Mode.
Address Family Mode (IPv4 unicast and VRF).
Command Default Level
Level: 12.
Usage Guideline
The purpose of this command is to eliminate the advertising of the unstable routes and thus to avoid
unstable of the network caused by flapping routes.
When a prefix is removed or is added, BGP increases the penalty of the route by 1000. When the
attribute of a received route has changes, BGP increases the penalty of the route by 500.
