peer reflect-client (BGP-IPv4 multicast address family view) (group)

Function

The peer reflect-client command configures a device as the RR and its peer group as the client.

The undo peer reflect-client command cancels the exiting configuration.

By default, there is no RR in an AS.

Format

Usage Guidelines

Usage Scenario

Full-meshed connections need to be established between IBGP peers to ensure the connectivity between the MBGP peers. If an MBGP network is large, it is costly to establish a fully-meshed network.

The VRP allows users to configure an RR in order to solve this problem. One MBGP peer is configured as the RR. Other MBGP peers are configured as clients. Each client establishes a peer relationship with the RR to exchange routing information. The RR transmits (reflects) routing information among the clients.

Example

# Configure a peer group named test as a client of an RR.
