5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide To set the preference value to 12 for all BGP routes from neighbor 10.1.1.1, use the following distance command. (Routing)(Config-router)#distance 12 10.1.1.1 0.0.0.0 To set the preference value of all routes within 100.0.0.0/8 from any neighbor, use the following distance command. (Routing)(Config)#ip prefix-list pfx-list2 permit 100.0.0.0/8 ge 8 (Routing)(Config)#router bgp 1 (Routing)(Config-router)#distance 25 0.0.0.0 255.255.255.255 pfx-1ist2 11-27 distance BGP (BGP Router Config) Use this command to set the preference, (also known as administrative distance), of BGP routes. Different distance values can be configured for routes learned from external peers, routes learned from internal peers, and BGP routes locally originated. A route with a lower preference value is preferred to a route with a higher preference value to the same destination. Routes with a preference of 255 may not be selected as best routes and used for forwarding. The change to the default BGP distances does not affect existing routes. To apply a distance change to existing routes, you must force the routes to be deleted from the RIB and relearned, either by resetting the peers from which the routes are learned or by disabling and reenabling BGP. Use the no command to set the default route preference value of BGP routes in the router. distance bgp external-distance internal-distance local-distance no distance bgp Parameters external-distance internal-distance local-distance The preference value for routes learned from external peers. The range is 1 to 255. The preference value for routes learned from internal peers. The range is 1 to 255. The preference value for locally-originated routes. The range is 1 to 255. Default The default is as follows: external - 20, internal - 200, local - 200.
