Multicast Listener Discovery (MLD) is a protocol used by an IPv6 host to register its IP multicast group membership with a router. To receive multicast traffic, a host must explicitly join a multicast group by sending an MLD report; then, the traffic is forwarded to that host. Periodically, the router queries the multicast group to see if the group is still in use. If the group is still active, a single IP host responds to the query, and group registration is maintained.
NoteThis release does not support MVR, PVLAN, VLAN Aggregation, and Multicast Troubleshooting tools for MLD/IPv6.
