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)). It can also explicitly express that it does not want to
receive the IPv6 multicast data that Source 2 sends to G (denoted as (S2, G)). As a result, Host B receives
only IPv6 multicast data from Source 1.
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, which include the time that the router waits before switching to the Include
•
mode after an IPv6 multicast address times out, and the source timer for source recording.

MLD support for VPNs

MLD maintains group memberships on a per-interface base. After receiving an MLD message on an
interface, MLD processes the packet within the VPN to which the interface belongs. MLD only
communicates with other multicast protocols within the same VPN instance.

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.
