MLD Snooping
Multicast Listener Discovery (MLD) snooping operates on IPv6 traffic and performs
a similar function to IGMP snooping for IPv4. That is, MLD snooping dynamically
configures switch ports to limit IPv6 multicast traffic so that it is forwarded only to
ports with users that want to receive it. This reduces the flooding of IPv6 multicast
packets in the specified VLANs.
