PGM Configuration Guidelines
Pragmatic General Multicast (PGM) allows the router to participate in defined PGM router assistance functions between PGM-enabled sources and receivers. Although PGM is a transport layer protocol and does not do IP packet routing, PGM must be explicitly configured on the router.
To enable PGM globally on the router, include the pgm statement:
You can include this statement at the following hierarchy levels:
- [edit protocols]
- [edit logical-systems logical-system-name protocols]
To trace the operation of PGM, include the traceoptions statement:
You can include this statement at the following hierarchy levels:
You can specify the following PGM-specific options in the 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.
By default, PGM is enabled on every interface of the router, but global, explicit configuration is required. No options are available for PGM operation.
