• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain can be interoperable at the network layer.

Configuring MLD SSM mapping entries
You can perform this configuration task multiple times to map an IPv6 multicast group to different IPv6
multicast sources.
On a device that supports both MLD snooping and MLD, if you enable MLDv2 on a VLAN interface ,
configure a port in the VLAN as a simulated host, the simulated host will send MLDv2 reports even if you
did not specify an IPv6 multicast source in the mld-snooping host-join command. In this case, the
corresponding IPv6 multicast group will not be created based on the configured MLD SSM mapping.

Configuring MLD proxying
This section describes how to configure MLD proxying.
Configuration prerequisites
Before you configure the MLD proxying feature, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.
• Enable IPv6 multicast routing.
