Enabling IGMP proxying
Restrictions and guidelines
Enable IGMP proxying on the receiver-side interfaces.
On an interface enabled with IGMP proxying, only the igmp version command takes effect and other IGMP commands do not take effect.
If you enable both IGMP proxying and a multicast routing protocol (such as PIM or MSDP) on the same device, the multicast routing protocol does not take effect.
In IGMPv1, the DR is elected by PIM and acts as the IGMP querier. Because PIM does not take effect on a proxy device, a router interface running IGMPv1 cannot be elected as the DR. To ensure that the downstream receiver hosts on the router interface can receive multicast data, you must enable multicast forwarding on the interface. For more information, see "Enabling multicast forwarding on a non-querier interface."
