Example console(config-router)#bgp always-compare-med bgp client-to-client reflection (BGP Router Configuration) Use the bgp client-to-client reflection command to enable 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 iBGP mesh, the route reflector does not reflect to the clients. Syntax bgp client-to-client reflection no bgp client-to-client reflection Default Configuration Client-to-client reflection is enabled by default when a router is configured as a route reflector. Command Mode BGP Router Configuration mode User Guidelines 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 influenced by the IGP metric of the route to reach the BGP next hop. Since a client's IGP distance to a given next hop may differ from route reflector's IGP distance, a route reflector may not re-advertise 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 clients are fully meshed, there is no need for the cluster's route reflectors to reflect client routes to other clients within the cluster. When client-to-client reflection is disabled, a route reflector continues to reflect routes from non-clients to clients and from clients to non-clients. Layer 3 Routing Commands 1289
