Configuring an RR and Specifying Its Clients
RRs reflect routes between clients, and therefore IBGP connections do not need to be established between the clients.
Context
In an AS, one router functions as an RR, and the other routers function as its clients. The clients establish IBGP connections with the RR. The RR and its clients form a cluster. The RR transmits or reflects routes among clients, but the clients do not need to establish any IBGP connections between each other.
An RR is easy to configure because it needs to be configured only on the router that functions as a reflector 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 ipv6-family unicast
The IPv6 unicast address family view is displayed.
- Run peer { ipv6-address | ipv4-address | group-name } reflect-client
An RR and its clients are configured.
The router where the peer reflect-client command is run functions as the RR, and specified peers or peer groups function as the clients.
reflect-client configured in an address family is valid in this family address and cannot be inherited by other address families.
- Run commit
The configuration is committed.
