Version 9.2(1.0) 8.2.1.0 7.4.1.0 Description Introduced on the Z9500. Introduced on the E-Series ExaScale. Introduced Usage Information The autonomous systems configured in this command are visible to the EBGP neighbors. Each autonomous system is fully meshed and contains a few connections to other autonomous systems. The next hop, MED, and local preference information is preserved throughout the confederation. The system accepts confederation EBGP peers without a LOCAL_PREF attribute. The software sends AS_CONFED_SET and accepts AS_CONFED_SET and AS_CONF_SEQ. bgp dampening Enable BGP route dampening and configure the dampening parameters. C9000 Series Syntax bgp dampening [half-life reuse suppress max-suppress-time] [routemap map-name] To disable route dampening, use the no bgp dampening [half-life reuse suppress max-suppress-time] [route-map map-name] command. Parameters half-life reuse suppress max-suppresstime (OPTIONAL) Enter the number of minutes after which the Penalty is decreased. After the router assigns a Penalty of 1024 to a route, the Penalty is decreased by half after the half-life period expires. The range is 1 to 45. The default is 15 minutes. (OPTIONAL) Enter a number as the reuse value, which is compared to the flapping route's Penalty value. If the Penalty value is less than the reuse value, the flapping route is once again advertised (or no longer suppressed). The range is 1 to 20000. The default is 750. (OPTIONAL) Enter a number as the suppress value, which is compared to the flapping route's Penalty value. If the Penalty value is greater than the suppress value, the flapping route is no longer advertised (that is, it is suppressed). The range is 1 to 20000. The default is 2000. (OPTIONAL) Enter the maximum number of minutes a route can be suppressed. The default is four times the half-life value. The range is 1 to 255. The default is 60 minutes. Border Gateway Protocol 569
