PGM Configuration Statements

PGM allows the router to participate in defined PGM router assistance functions between PGM-enabled sources and receivers. Because PGM is a transport layer protocol and is not directly concerned with IP packet routing, you do not need to explicitly configure PGM on the router.

To trace the operation of PGM, include the pgm statement:

pgm {

    traceoptions { 

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

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

        flag flag <flag-modifier>; 

    }

}

You can specify the following PGM-specific options in the PGM flag statement:

• all—Trace all PGM packets.
• init—Trace all PGM initialization events.
• packets—Trace all PGM packet processing.
• parser—Trace all PGM parser processing.
• route-socket—Trace all PGM route-socket events.
• show—Trace all PGM show command servicing.
• state—Trace all PGM state transitions.

You can configure this statement at the following hierarchy levels:

• [edit protocols]
• [edit logical-routers logical-router-name protocols]

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

By default, PGM is enabled on every interface of the router. No explicit configuration is required. No options are available for PGM operation.
