    Unconfiguring PGM from all interfaces unconfigures PGM on the router.


  Interface subcommands:

    [no] ip pgm router
        Configures PGM on a given interface of the router. Multicast 
        routing should be enabled on the router before configuring PGM. 
        PIM should be configured on each PGM interface.


  Debug Commands:
