MLD for Subscriber Access, Release 10.1
The Multicast Listener Discovery (MLD) Protocol
manages the membership of hosts and routers in multicast groups. IP
version 6 (IPv6) multicast routers use MLD to learn, for each of their
attached physical networks, which groups have interested listeners.
Each router maintains a list of host multicast addresses that have
listeners for each subnet, as well as a timer for each address. However,
the router does not need to know the address of the listeners—just
the address of the hosts. The router provides addresses to the multicast
routing protocol it uses; this ensures that multicast packets are
delivered to all subnets where there are interested listeners. In
this way, MLD is used as the transport for the Protocol Independent
Multicast (PIM) protocol.
