Switches forward multicast frames out of all ports in a VLAN by default, even though there may be only some interested hosts, which is a waste of bandwidth. MLD Snooping enables switches to use information in MLD packets to generate a forwarding table that associates ports with multicast groups so that when they receive multicast frames, they can forward them only to interested receivers. Enable MLD Snooping MLD is automatically enabled when you enable IPv6 PIM, but MLD Snooping must be explicitly enabled.
