NOOPING
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.
There are two versions of the MLD protocol, version 1 and version 2.
MLDv1 control packets include Listener Query, Listener Report, and
Listener Done messages (equivalent to IGMPv2 query, report, and leave
messages). MLDv2 control packets include MLDv2 query and report
messages, as well as MLDv1 report and done messages.
Remember that IGMP Snooping and MLD Snooping are independent
functions, and can therefore both function at the same time.
Due to an ASIC limitation in the ECS4110-52T, MLDv2 reports with
N :
OTE
source list is not supported. The switch can only process IS_EX (is
excluded), TO_EX (change to excluded), and TO_IN (change to included)
records without source list.
