Command Mode Usage Information ROUTER-BGP If a cluster contains only one route reflector, the cluster ID is the route reflector's router ID. For redundancy, a BGP cluster may contain two or more route reflectors. Without a cluster ID, the route reflector cannot recognize route updates from the other route reflectors within the cluster. The default format to display the cluster ID is A.B.C.D format. If you enter the cluster ID as an integer, an integer displays. The no version of this command resets the value to the default. NOTE: To configure these settings for a non default VRF instance, you must first enter the ROUTERCONFIG-VRF sub mode using the following commands: 1 Enter the ROUTER BGP mode using the router bgp as-number command. 2 From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name command. Example OS10(conf-router-bgp-10)# cluster-id 3.3.3.3 Supported Releases 10.3.0E or later bgp dampening Enables BGP route-flap dampening and configures the dampening parameters. Syntax Parameters bgp dampening [half-life | reuse-limit | suppress-limit | max-suppress-time | route-map-name] • half-life - (Optional) Enter the half-life time, in minutes, after which the penalty decreases. After the router assigns a penalty of 1024 to a route, the penalty decreases by half after the half-life period expires, from 1 to 45. • reuse-limit - (Optional) Enter a reuse-limit value, which compares to the flapping route's penalty value. If the penalty value is less than the reuse value, the flapping route advertises again and is not suppressed, from 1 to 20000. • suppress-limit - (Optional) Enter a suppress-limit value, which compares to the flapping route's penalty value. If the penalty value is greater than the suppress value, the flapping route is no longer advertised, from 1 to 20000. • max-suppress-time - (Optional) Enter the maximum number of minutes a route is suppressed, from 1 to 255. • route-map-name - (Optional) Enter the name of the route-map. Defaults Command Mode Usage Information Example half-life 15; reuse-limit 750; suppress-limit 2000; max-suppress-time 60 ROUTER-BGP-AF To reduce the instability of the BGP process, setup route flap dampening parameters. After setting up the dampening parameters, clear information on route dampening and return the suppressed routes to the Active state. You can also view statistics on route flapping or change the path selection from Default Deterministic mode to Non-Deterministic mode. The no version of this command resets the value to the default.
