5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide Parameters None. Default The default is a MED setting to only compare paths with peers within the same AS. Command Mode • BGP Router Config • IPv6 Address Family Config • IPv4 VRF Address Family Config 11-12 bgp bestpath as-path ignore To ignore the AS-PATH length in the best path calculation during the decision process, use the bgp bestpath as-path ignore command in Router Configuration mode. For IPv6 routes, configure this command in Address Family IPv6 mode. To influence ECMP route calculations, configure the AS-PATH parameter. Use the no command to revert to the default behavior, where AS-PATH length is not ignored in the BGP best path calculation. bgp bestpath as-pat ignore no bgp bestpath as-pat ignore Parameters None. Default The default is a behavior setting to avoid ignoring AS-PATH length in BGP best path calculations. Command Mode • BGP Router Config • IPv6 Address Family Config • IPv4 VRF Address Family Config 11-13 bgp client-to-client reflection By default, a route reflector reflects routes received from its clients to its other clients. However, if a route reflector's clients have a full BGP mesh, the route reflector does not reflect to the clients. The bgp clientto-client refiection command enables client-to-client reflection for IPv4, lPV6, or IPv4 VRF routes. Route reflection can change the routes clients select. A route reflector only reflects those routes it selects as best routes. Best route selection can be infiuenced by the IGP metric of the route to reach the BGP next hop. Since a clients IGP distance to a given next hop may differ from the route refiectors IGP distance, a route reflector may not readvertise a route a client would have selected as best in the absence of route reflection. One way to avoid this effect is to fully mesh the clients within a cluster. When 1031
