ip igmp-proxy
When used without parameters, this Layer 3 command enables/disables the IGMP Proxy feature on the
selected port. To enable the feature, you must also enable multicast forwarding. Also, make sure that
there are no multicast routing protocols enabled on the router.
IGMP Proxy is used by the IGMP router to enable the system to issue IGMP host messages on behalf
of hosts that the system discovered through standard IGMP router interfaces. These commands are
valid only when you first enable IGMP Proxy on the interface. With IGMP Proxy enabled, the system
acts as proxy to all the hosts residing on its router interfaces.
