Functional Notes
This command is used in IP multicast stub applications in conjunction with the ip mcast-stub
helper-address, ip mcast-stub upstream, and ip mcast-stub downstream commands. When enabled,
the interface becomes a helper forwarding interface. The IGMP host function is dynamically enabled and
the interface becomes the active upstream interface, enabling the router to perform as an IGMP proxy.
