Configuration prerequisites
Before you configure the MLD SSM mapping feature, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain can be interoperable at the network layer.
• Configure MLD basic functions.
Enabling MLD SSM mapping
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Enable the MLD SSM
mapping feature.
mld ssm-mapping enable Disabled by default
NOTE:
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.
Configuring MLD SSM mappings
By performing this configuration multiple times, you can map an IPv6 multicast group to different IPv6
multicast sources.
To configure an MLD SSM mapping:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MLD view. mld N/A
3. Configure an MLD SSM
mapping.
ssm-mapping ipv6-group-address
prefix-length ipv6-source-address No MLD mappings are configured
by default.
