non-querier downstream interface
igmp proxying forwarding
Required
Disabled by default.
On a multi-access network with more than one IGMP proxy device, you cannot enable multicast
forwarding on any other non-querier downstream interface after one of the downstream interfaces of
these IGMP proxy devices has been elected as the querier. Otherwise, duplicate multicast flows may be
received on the multi-access network.
