Command Mode BGP Router IPv4 Address Family 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. In BGP Router Configuration mode, this command only affects advertisement of IPv4 routes. The same command is available in AddressFamily IPv6 Configuration mode for IPv6 routes. Command History Introduced in version 6.2.0.1 firmware. Example console(config-router-af-ipv4)#bgp client-to-client reflection bgp client-to-client reflection (IPv6 Address Family 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.
