Configure MSDP Peers

An MSDP router must know which routers are its peers. You define the peer relationships explicitly by configuring the neighboring routers that are the MSDP peers of the local router. After peer relationships are established, the MSDP peers exchange messages to advertise active multicast sources. You must configure at least one peer for MSDP to function.

To configure MSDP peers, include the peer statement:

peer address { 

    export [ policy-names ]; 

    import [ policy-names ];

    local-address address; 

    traceoptions {

        file name <replace> <size size> <files number> <no-stamp> 

            <(world-readable | no-world-readable)>;

        flag flag <flag-modifier> <disable>; 

    }

}

The peer and the local-address statements are required. You can configure MSDP peers globally (at the [edit protocols msdp] hierarchy level) or in a group (at the [edit protocols msdp group group-name] level). If you configure them in a group, each individual peer inherits all group-level options.
