DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Command Default Level Usage Guideline Level: 8. (EI Mode Only Command) By default, the clients of a router reflector are not required to be fully meshed and the routes from a client are reflected to other clients. However, if the clients are fully meshed, route reflection is not required. In this case, use the no bgp client-to-client reflection command to disable client-to-client reflection. Use the show ip bgp reflection command to verify your settings. Example This example shows how to enable the route reflector function of the local router. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 100 DXS-3600-32S(config-router)#bgp client-to-client reflection DXS-3600-32S(config-router)# 7-13 bgp cluster-id This command is used to configure the cluster ID of the route reflector. To remove the cluster ID, use the no form of this command. bgp cluster-id CLUSTER-ID no bgp cluster-id Parameters CLUSTER-ID Specifies the cluster ID, in the IPv4 address format, for the router reflector. Default Command Mode Command Default Level Usage Guideline By default, this value is the local router's ID. Router Configuration Mode. Level: 8. (EI Mode Only Command) When a single route reflector is deployed in a cluster and the cluster ID of the route reflector is 0.0.0.0, the cluster is identified by the router ID of the route reflector. Otherwise, the cluster is identified by the cluster ID. This command is used to assign a cluster ID to a route reflector. Multiple route reflectors are deployed in a cluster to increase redundancy and to avoid a single point of failure. When multiple route reflectors are configured in a cluster, they must be configured with the same cluster ID. This allows all route reflectors, in the cluster, to recognize updates from the peers in the same cluster and reduces the number of updates that needs to be stored in BGP routing tables. This command is only required for the reflector and not for the client. Use the show ip bgp reflection command to verify your settings. Example In the following example, the local router is one of the route reflectors serving the cluster. It is configured with a cluster ID to identify the cluster. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 100 DXS-3600-32S(config-router)#neighbor 172.18.0.16 route-reflector-client DXS-3600-32S(config-router)#bgp cluster-id 10.0.0.2 DXS-3600-32S(config-router)# 72
