Configuring and Viewing IGMP Proxy
Use the following commands to configure the upstream VLAN routing
interface as an IGMP proxy. The IGMP proxy issues host messages on behalf
of the hosts that have been discovered on IGMP-enabled interfaces. The
upstream interface is the interface closest to the root multicast router, which
should be running IGMP.
NOTE: Configure only the upstream interface as the IGMP proxy. IGMP should
be enabled on all downstream interfaces. IP routing and IP multicast must be
enabled on the switch for the IGMP proxy feature to operate.
