interface view or Layer 2

enter port group view.
3. Enable IPv6 multicast source
port filtering.

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. When the switch receives such IPv6 multicast traffic, one of the following
occurs:
If the function of dropping unknown IPv6 multicast data is disabled, the switch floods unknown IPv6
•
multicast data in the VLAN that the data belongs to.
• If the function of dropping unknown IPv6 multicast data is enabled, the switch drops all received
unknown IPv6 multicast data.
For a device that supports both drop-unknown and mld-snooping drop-unknown commands, do not
configure them at the same time. If you If you enable this function in MLD-snooping view, you should not
enable or disable it in VLAN view, or vice versa.
The following matrix shows the feature and the MSR router compatibility:
