By default, no IPv6 multicast
group policies exist on a port.
Hosts attached to the port can join
any IPv6 multicast groups.
Enabling IPv6 multicast source port filtering
This feature enables the device to discard all IPv6 multicast data packets and to accept IPv6
multicast protocol packets. You can enable this feature on ports that connect to only IPv6 multicast
receivers.
You can enable multicast source port filtering for the specified ports in MLD-snooping view or for a
port in interface view. For a port, the configuration in interface view has the same priority as the
configuration in MLD-snooping view, and the most recent configuration takes effect.

Enabling dropping unknown IPv6 multicast data
Unknown IPv6 multicast data refers to IPv6 multicast data for which no forwarding entries exist in the
MLD snooping forwarding table. This feature enables the device only to forward unknown IPv6
multicast data to the router port. If the device does not have a router port, unknown IPv6 multicast
data will be dropped.
If you do not enable this feature, the unknown IPv6 multicast data is flooded in the VLAN to which the
data belongs.
