Multicast Listener Discovery Concepts
Multicast Listener Discovery (MLD) protocol enables IPv6 routers to discover multicast
listeners, the nodes that are configured to receive multicast data packets, on its directly
attached interfaces. The protocol specifically discovers which multicast addresses are of
interest to its neighboring nodes and provides this information to the active multicast routing
protocol that determines the flow of multicast data packets.
listeners, the nodes that are configured to receive multicast data packets, on its directly
attached interfaces. The protocol specifically discovers which multicast addresses are of
interest to its neighboring nodes and provides this information to the active multicast routing
protocol that determines the flow of multicast data packets.
Periodically, the multicast router sends general queries requesting multicast address listener
information from systems on an attached network. These queries are used to build and
refresh the multicast address listener state on the attached networks. In response to the
queries, multicast listeners reply with membership reports. These membership reports
specify their multicast addresses listener state and their desired set of sources with
current-state multicast address records.

The multicast router also processes unsolicited filter- mode-change records and
source-list-change records from systems that want to indicate interest in receiving or not
receiving traffic from particular sources.
