BGP Commands

configure /jointfilesconvert/484795/bgp peer-group dampening

configure /jointfilesconvert/484795/bgp peer-group <peer-group-name> {address-family [ipv4-unicast |

ipv4-multicast]} dampening {{half-life <half-life-minutes> {reuse-limit

<reuse-limit-number> supress-limit <suppress-limit-number> max-suppress

<max-suppress-minutes>}} | policy-filter [<policy-name> | none]}

Description

Configures route flap dampening for a BGP peer group.

Syntax Description

Default

This feature is disabled by default.

If no address family is specified, IPv4 unicast is the default.

Usage Guidelines

The half life is the period of time, in minutes, during which the accumulated penalty of a route is

reduced by half. The range is 1 to 45 minutes, and the default is 15 minutes.

The reuse limit is the penalty value below which a route will be used again. The range is 1-20,000, and

the default is 750.

The suppress limit is the penalty value above which a route will be suppressed. The range is 1-20,000,

and the default is 2,000.

The maximum hold down time is the maximum time a route can be suppressed, no matter how

unstable it has been, as long as it no longer flaps. The range is 1-255 minutes, and the default is 4 * the

half life.

Instead of explicitly configuring the dampening parameters using the command line, you can associate

a policy using the

policy-filter option. Multiple sets of parameters can be supplied using a policy.

Use the following command to disable route flap dampening for a BGP peer-group:

configure /jointfilesconvert/484795/bgp peer-group <peer-group-name> no-dampening

peer-group-name Specifies a peer group

address-family The address family. BGP supports two address families: IPv4 Unicast and

IPv4 Multicast

half-life-minutes Specifies the dampening half life.

reuse-limit-number Specifies the reuse limit.

suppress-limit-number Specifies the suppress limit.

max-suppress-minutes Specifies the maximum hold down time.

policy-name Specifies a policy

none Removes any policy association.
