MLD Snooping

Multicast Listener Discovery (MLD) Snooping is an IPv6 function used similarly to IGMP snooping in IPv4. It is used to
discover ports on a VLAN that are requesting multicast data. Instead of flooding all ports on a selected VLAN with
multicast traffic, MLD snooping will only forward multicast data to ports that wish to receive this data through the use
of queries and reports produced by the requesting ports and the source of the multicast traffic.
MLD snooping is accomplished through the examination of the layer 3 part of an MLD control packet transferred
between end nodes and a MLD router. When the Switch discovers that this route is requesting multicast traffic, it adds
the port directly attached to it into the correct IPv6 multicast table, and begins the process of forwarding multicast
