MSDP Configuration Guidelines

To configure the Multicast Source Discovery Protocol (MSDP), include statements at the [edit protocols msdp] or [edit logical-routers logical-router-name protocols msdp] hierarchy level of the configuration:

[edit]

protocols {

    msdp {

        active-source-limits {

            maximum number;

            threshold number;

        }

        data-encapsulation <(disable | enable)>;

        disable;

        export [ policy-names ]; 

        import [ policy-names ];

        local-address address ;

        rib-group group-name ;

        traceoptions {

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

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

            flag flag <flag-modifier > <disable>;

For an overview of logical routers and a detailed example of logical router configuration, see the logical routers chapter of the JUNOS Internet Software Feature Guide.

By default, MSDP is disabled.

This chapter describes the following tasks for configuring MSDP:

• Minimum MSDP Configuration
• Enable MSDP
• Configure MSDP Peers
• Configure MSDP Groups
• Configure MSDP Mesh Groups
• Configure MSDP Authentication Key
• Configure MSDP Routing Policy
• Configure Multiple Rendezvous Points in a Domain
• Configure MSDP Data Encapsulation
• Configure MSDP Active Source Limits
• Disable MSDP
• Trace MSDP Protocol Traffic

For a configuration example, see Example: Configure MSDP.
