Multicast Listener Discovery snooping
In IPv6 networks, Multicast Listener Discovery (MLD) snooping performs a similar function
as IGMP in IPv4 networks. With MLD snooping, IPv6 multicast data is selectively forwarded
to ports that are configured to receive the data, instead of being flooded to all ports in
a VLAN. The ports are determined by snooping IPv6 multicast control packets.
A multicast listener is a device that is configured to receive IPv6 multicast packets. MLD
is used by IPv6 multicast routers to discover the presence of multicast listeners on its
directly-attached links and to discover which multicast packets are of interest to
neighboring devices.
The MLD protocol is derived from IGMP. MLD version 1 (MLDv1) is equivalent to IGMPv2,
and 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.
Configure MLD snooping automatically with MLD Plus
mode
MLD Plus mode lets you automatically configure MLD snooping, which is used to build
forwarding lists for IPv6 multicast traffic.
You can also configure MLD snooping manually (see Configure MLD snooping manually
on page 271).
