Configuring a Route Reflector and Specifying Clients
RRs can reflect routes between clients, and clients do not need to establish IBGP connections.
Context
In an AS, one router functions as an RR, the other routers function as clients. IBGP connections are established between the RR and its clients. The RR and its clients form a cluster. The RR transmits (or reflects) routes between clients, and clients do not need to establish IBGP connections.
An RR simplifies configurations because all configurations need to be configured only on the RR and clients do not need to know that they are clients.
Procedure
- Run system-view
The system view is displayed.
- Run bgp as-number
The BGP view is displayed.
- Run ipv4-family unicast
The IPv4 unicast address family view is displayed.
- Run peer { ipv4-address | group-name } reflect-client
An RR and its client are configured.
The router on which the peer reflect-client command is run serves as the RR, and the specified peer or peer group functions as a client.
The configurations of RRs and clients in an address family are valid only in this address family and cannot be inherited by other address families. Therefore, configure RRs and clients in the required address family.
- Run commit
The configuration is committed.
