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
Enable dropping unknown IPv6
multicast data

Configuring MLD Report Suppression

When a Layer 2 device receives an MLD report from an IPv6 multicast group member, the Layer 2
device forwards the message to the Layer 3 device directly connected with it. Thus, when multiple
members belonging to an IPv6 multicast group exist on the Layer 2 device, the Layer 3 device directly
connected with it will receive duplicate MLD reports from these members.
