CAUTION:
On a multi-access network with more than one MLD proxy devices, you cannot enable IPv6 multicast
forwarding on any other non-querier downstream interface after one of the downstream interfaces of
these MLD proxy devices has been elected as the querier. Otherwise, duplicate multicast flows might be
received on the multi-access network.
