When MLDv2 runs on the hosts and routers, Host B can explicitly express its interest in the IPv6 multicast
data that Source 1 sends to G (denoted as (S1, G)), rather than the IPv6 multicast data that Source 2
sends to G (denoted as (S2, G)). Only IPv6 multicast data from Source 1 is delivered to Host B.
Enhancement in MLD state
A multicast router that is running MLDv2 maintains the multicast address state for each multicast address
on each attached subnet. The multicast address state consists of the following information:
Filter mode—Router keeps tracing the Include or Exclude state.
List of sources—Router keeps tracing the newly added or deleted IPv6 multicast source.
Timers—Filter timers, including the time that the router waits before switching to the Include mode
after an IPv6 multicast address times out, the source timer for source recording, and so on.

Protocols and standards

RFC 2710, Multicast Listener Discovery (MLD) for IPv6
RFC 3810, Multicast Listener Discovery Version 2 (MLDv2) for IPv6

Configuring basic MLD functions
Before you configure basic MLD functions, complete the following tasks:
Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices can be
interoperable at the network layer.
Configure IPv6 PIM.
Determine the MLD version.
Determine the IPv6 multicast group address and IPv6 multicast source address for static group
member configuration.
Determine the ACL rule for IPv6 multicast group filtering.

Enabling MLD

Enable MLD on the interface on which IPv6 multicast group memberships are created and maintained.
To enable MLD:
Enabling MLD
Specifying the MLD version
Configuring an interface as a static member interface
Configuring an IPv6 multicast group filter
Enabling MLD fast-leave processing
