multicast address, filter mode, and source list. Such an entry is a collection of members in the same 
multicast group on each downstream interface.  

A proxy device performs host functions on the upstream interface based on the database. It 
responds to the queries according to the information in the database or sends join/leave messages 
when the database changes. The 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 that the interface belongs to. If MLD that runs in 
a VPN needs to exchange information with another multicast protocol, it passes the information only 
to the protocol that runs in this VPN. 

Protocols and standards 

•

 

RFC 2710, 

Multicast Listener Discovery (MLD) for IPv6

 

•

 

RFC 3810, 

Multicast Listener Discovery Version 2 (MLDv2) for IPv6

 

•

 

RFC 4605, 

Internet Group Management Protocol (IGMP)/Multicast Listener Discovery 

(MLD)-Based Multicast Forwarding ("IGMP/MLD Proxying")

 

MLD configuration task list 

For the configuration tasks in this section, the following rules apply: 

•

 

The configurations made in MLD view are effective on all interfaces. The configurations made in 
interface view are effective only on the current interface.  

•

 

A configuration made in interface view always has priority over the same global configuration in 
MLD view. If you do not make the configuration in interface view, the corresponding global 
configuration made in MLD view applies to the interface.
