Configuration Guide MLD Snooping Configuration
demote the timer to configured MLD query-max-response-time. When the
timer value is reduced to "0", it is considered that there is no longer any
listener of the port receiving multicast stream. Layer 2 multicast equipment
will delete the port from MLD Snooping forwarding-table.

Whenever receiving MLD group-specific query message, layer 2 multicast
equipment will update aging timers of all listener ports in the specific group,
and demote the timer to configured MLD query-max-response-time. When
the timer value is reduced to "0", it is considered that there is no longer any
listener of the port receiving multicast stream. Layer 2 multicast equipment
will delete the port from MLD Snooping forwarding-table.

When receiving MLD group-specific source query message, the aforesaid
two kinds of timers will not be updated.
2. MLD REPORT
A host will send MLD membership report to MLD queriers under following conditions:

When receiving MLD (group-general or group-specific) query message, the
listener hosts of IPv6 multicast group will respond with MLD membership
report message.

When joining certain IPv6 multicast group, a host will actively send MLD
membership report message to MLD queriers to announce its joining in this
IPv 6 multicast group.
A switch transmits through all routers in VLAN the MLD membership report message
being received, resolve the IPv6 multicast group addresses which hosts will join, and
process the receive port in the following ways:

If the forwarding-table corresponding to this IPv6 multicast group does not
exist, a forwarding-table should be created. And the port should be added
as a dynamic listener port to the list of outgoing ports and its aging timer
should be enabled.

If the forwarding-table corresponding to this IPv6 multicast group already
exists, but the list of its outgoing ports does not include this port, the port
should be added as a dynamic listener port to the list of outgoing ports and
its aging timer should be enabled.

If the forwarding-table corresponding to this IPv6 multicast group already
exists, and the list of its outgoing ports includes this dynamic listener port,
then its aging timer should be reset.
3. MLD LEAVE
When leaving IPv6 multicast group, a host will send MLD leave message to
notify the multicast router that it has left certain IPv6 multicast group. A switch
will directly forward to router port the MLD leave message it receives from
