CAUTION:
On a multi-access network with more than one IGMP proxy device, do not 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 might be received
on the multi-access network.
