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.
This switch supports MLD protocol version 1. MLDv1 control packets
include Listener Query, Listener Report, and Listener Done messages
(equivalent to IGMPv2 query, report, and leave messages).
Remember that IGMP Snooping and MLD Snooping are independent
functions, and can therefore both function at the same time.
