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.
