If MLDv2 is enabled on a VLAN interface, and if a port in that VLAN is configured as a simulated host, 

the simulated host will send MLDv2 reports even if you did not specify an IPv6 multicast source when 

configuring simulated joining with the mld-snooping host-join command. In this case, the 

corresponding IPv6 multicast group will not be created based on the configured MLD SSM mappings. 

For details about the mld-snooping host-join command, refer to MLD Snooping Commands in the IP 

Multicast Volume. 

 

Before configuring the MLD proxying feature, complete the following tasks: 

z 

Configure any IPv6 unicast routing protocol so that all devices in the domain are interoperable at 

the network layer. 

z 

Enable IPv6 multicast routing. 

You can enable MLD proxying on the interface in the direction toward the root of the multicast 

forwarding tree to make the device serve as an MLD proxy.  

Follow these steps to enable MLD proxying: 

Enter system view 

Enter interface view 

interface interface-type 
interface-number 

Enable the MLD proxying 
feature 

Required 

Disabled by default 

 

z 

Each device can have only one interface serving as the MLD proxy interface. 

z 

You cannot enable MLD on interfaces with MLD proxying enabled. Moreover, only the mld 

require-router-alert, mld send-router-alert, and mld version commands can take effect on such 

interfaces.  

z 

You cannot enable other IPv6 multicast routing protocols (such as IPv6 PIM-DM or IPv6 PIM-SM) 

on interfaces with MLD proxying enabled, or vice versa. However, the source-lifetime, 

source-policy, and ssm-policy commands configured in IPv6 PIM view can still take effect. 

z 

You cannot enable MLD proxying on a VLAN interface with MLD snooping enabled, or vice versa.
