Configuring IPv6 multicast forwarding on a downstream
interface
Typically, to avoid duplicate multicast flows, only queriers can forward IPv6 multicast traffic. On MLD
proxy devices, a downstream interfaces must be a querier in order to forward IPv6 multicast traffic to
downstream hosts. If the interface has failed in the querier election, you must manually enable IPv6
multicast forwarding on this interface.
On a shared-media 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 shared-media network.

Displaying and maintaining MLD
CAUTION:
The reset mld group command might cause IPv6 multicast transmission failures.
To display and maintain MLD:
