Protocols And Standards; Mld Configuration Task List; Configuring Basic Mld Functions; Enabling Mld - HP 5920 series Configuration Manual

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.

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
