IPv6 MLD Snooping Commands

In IPv6, Multicast Listener Discover (MLD) snooping performs functions
similar to IGMP snooping in IPv4. With MLD snooping, IPv6 multicast data
is selectively forwarded to a list of ports that want to receive the data, instead
of being flooded to all ports in a VLAN. This list is constructed by snooping
IPv6 multicast control packets.
MLD is a protocol used by IPv6 multicast routers to discover the presence of
multicast listeners (nodes wishing to receive IPv6 multicast packets) on its
directly-attached links and to discover which multicast packets are of interest
to neighboring nodes. MLD is derived from IGMP. MLD version 1 (MLDv1)
is equivalent to IGMPv2. MLD version 2 (MLDv2) is equivalent to IGMPv3.
MLD is a subprotocol of Internet Control Message Protocol version 6
(ICMPv6), and MLD messages are a subset of ICMPv6 messages, identified
in IPv6 packets by a preceding Next Header value of 58.
PowerConnect switches can snoop on both MLDv1 and MLDv2 protocol
packets and bridge IPv6 multicast data based on destination IPv6 Multicast
MAC Addresses. The switch can be configured to perform MLD Snooping
and IGMP Snooping simultaneously. The PowerConnect implementation is
compliant to RFC 4541.
