Due to some possible restrictions, some receiver hosts on an SSM network may run MLDv1. To provide 

SSM service support for these receiver hosts, you need to configure the MLD SSM mapping feature on 

the last hop router. 

Before configuring the MLD SSM mapping feature, complete the following tasks: 

z 

Configure any IPv6 unicast routing protocol so that all devices in the domain can be interoperable 

at the network layer. 

z 

Configure MLD basic functions 

Follow these steps to enable the MLD SSM mapping feature: 

Enter system view 

Enter interface view 

interface interface-type 
interface-number 

Enable the MLD SSM mapping 
feature 

Required 

Disabled by default 

 

To ensure SSM service for all hosts on a subnet, regardless of the MLD version running on the hosts, 

enable MLDv2 on the interface that forwards IPv6 multicast traffic onto the subnet. 

 

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: 

Enter system view
