Configuring MLD SSM Mappings

By performing this configuration multiple times, you can map an IPv6 multicast group to different IPv6
multicast sources.
Follow these steps to configure an MLD SSM mapping:
To do...
Enter system view
Enter MLD view
Configure an MLD SSM
mapping
If MLDv2 is enabled on a VLAN interface of a 3Com Switch 4800G, 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.

Configuring MLD Proxying

Configuration Prerequisites

Before configuring the MLD proxying feature, complete the following tasks:
Configure any IPv6 unicast routing protocol so that all devices in the domain are interoperable at
the network layer.
Enable IPv6 multicast routing.

Enabling MLD Proxying

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:
To do...
Enter system view
Enter interface view
Enable the MLD proxying
feature
Use the command...
system-view
mld
ssm-mapping
ipv6-group-address
prefix-length
ipv6-source-address
Use the command...
system-view
interface interface-type
interface-number
mld proxying enable
