BGP Dampening Settings
This window is used to configure the Border Gateway Protocol (BGP) process’s dampening settings. The purpose
of this feature is to eliminate the dampening of routes and thus to avoid unstable networks caused by flapping
routes.
To view the following window, click
L3 Features > BGP > BGP Dampening Settings
, as shown below:
Figure 5-11022 BGP Dampening Settings window
The fields that can be configured are described below:
Parameter
Description
Dampening State
Use the drop-down menu to enable or disable the BGP dampening function’s state.
Half Life (1-45)
Enter the time (in minutes) after which the penalty of the reachable routes will be
down, by half. The default setting is 15 minutes.
Reuse (1-20000)
Enter a reuse value. If the penalty for a flapping route decreases enough to fall below
this value, the route is unsuppressed. The default setting is 750.
Suppress (1-20000)
Enter a suppress value. A route is suppressed when its penalty exceeds this limit.
The default setting is 2000.
Max Suppress Time
(1-255)
Enter the maximum time (in minutes) a route can be suppressed. The default setting
is 60 minutes.
Un Reachability Half
Life (1-45)
Enter the time (in minutes) after which the penalty of the unreachable routes will be
down, by half. The default setting is 15 minutes.
Route Map Action
Use the drop-down menu to select between
Route Map
and
Clear Route Map
. Route
Map sets the dampening running configuration while Clear Route Map withdraws the
route map configuration.
Route Map Name
Enter a route map name to be set or withdrawn. The default value is null.
