Router(config-router-af)#neighbor ip-address route-reflector-client

To configure the router as a BGP RR and configure the specified neighbor as its client, use the neighbor route-reflector-client command in address-family or router configuration mode.

Router(config-router)#neighbor {ip-address | peer-group-name} send-community [both | standard | extended]
