[no] ipv6 mld snooping [drop-unknown [vlan-shared | vlan-exclusive]]

Description

This command configures the drop unknown mode. While MLD snooping is enabled, the traffic will be forwarded only to ports that initiate an MLD request for multicast. Drop unknown mode can be a filter across all VLANs (vlan-shared) or per VLAN (exclusive-vlan). The default configuration is vlan-shared.

The no form of this command disables drop unknown mode on the switch.
