1404 Managing IPv4 and IPv6 Multicast
Configuring and Viewing IGMP Proxy

Beginning in Privileged EXEC mode, 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 feat ure to operate.
