Functional Notes

This command is used in IP multicast stub applications in conjunction with the ip mcast-stubhelper-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 unit to perform as an IGMP proxy. Refer to ip mcast-stubhelper-address <ip address> on page 389, ip mcast-stub downstream on page 791, and ip mcast-stub upstream on page 794 for more information.

Usage Examples

The following example sets the helper address as the IGMP proxy:

(config)#interface tunnel 1

(config-tunnel 1)#ip mcast-stub helper-enable
