Configuring 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:
With the function of dropping unknown IPv6 multicast data enabled, the switch drops all unknown
IPv6 multicast data received.
With the function of dropping unknown IPv6 multicast data disabled, the switch floods unknown
IPv6 multicast data in the VLAN to which the unknown IPv6 multicast data belongs.
Follow these steps to enable dropping unknown IPv6 multicast data in a VLAN:
To do...
Enter system view
Enter VLAN view
Use the command...
