Mld Support For Vpns; Protocols And Standards; Mld Configuration Task List; Configuring Basic Mld Functions - HP MSR2003 Configuration Manual

An MLD proxy device performs host functions on the upstream interface based on the membership
database. It responds to the MLD queries according to the information in the database or sends
report/done messages when the database changes. The MLD proxy device performs router functions on
the downstream interfaces by participating in the querier election, sending queries, and maintaining
memberships based on the reports.

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.
•
• 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.
•
