2. Enter interface view.
interface interface-type
interface-number
N/A
3. Enable the IGMP SSM mapping
feature.
igmp ssm-mapping enable Disabled by default
NOTE:
To ensure SSM service for all hosts on a subnet, regardless of the IGMP version running on the hosts,
enable IGMPv3 on the interface that forwards multicast traffic onto the subnet.
Configuring SSM mappings
By performing this configuration multiple times, you can map a multicast group to different multicast
sources.
To configure an IGMP SSM mapping:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter public network IGMP view. igmp N/A
3. Configure an IGMP SSM
mapping.
ssm-mapping group-address { mask |
mask-length } source-address No IGMP mappings are
configured by default.
Configuring IGMP proxying
Configuration prerequisites
Before you configure the IGMP proxying feature, complete the following tasks:
• Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Enable IP multicast routing.
Enabling IGMP proxying
You can enable IGMP proxying on the interface in the direction toward the root of the multicast
forwarding tree to make the device serve as an IGMP proxy.
To enable IGMP proxying:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
