This feature enables the device to drop all 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.
If you do not enable this feature, the unknown IPv6 multicast data is flooded in the VLAN to which the
data belongs.
For a VLAN enabled with this feature, the SIC-4GSW drops unknown IPv6 multicast data for the
VLAN.
To enable dropping unknown IPv6 multicast data for a VLAN:

Enabling MLD report suppression
This feature enables the Layer 2 device to forward only the first MLD report for an IPv6 multicast
group to its directly connected Layer 3 device. Other reports for the same group in the same query
interval are discarded. Use this feature to reduce the multicast traffic.
To enable MLD report suppression:
