Chapter 25 | Multicast Filtering Commands
MLD Snooping
– 704 –
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.
