Configuration prerequisites

Before you configure the IGMP SSM mapping feature, complete the following tasks:
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
•
network layer.
• Configure basic IGMP functions.

Enabling SSM mapping

To ensure SSM service for all hosts on a subnet, enable IGMPv3 on the interface that forwards multicast
traffic onto the subnet, regardless of the IGMP version running on the hosts.
To enable the IGMP SSM mapping feature:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the IGMP SSM
mapping feature.

Configuring SSM mappings

By performing this configuration multiple times, you can map a multicast group to different multicast
sources.
On a device that supports both IGMP snooping and IGMP, if you configure simulated joining on an
IGMPv3-enabled VLAN interface without specify any multicast source, the simulated member host still
sends IGMPv3 reports. In this case, the corresponding multicast group will not be created based on the
configured IGMP SSM mappings. For more information about the igmp-snooping host-join command,
see IP Multicast Command Reference.
To configure an IGMP SSM mapping:
Step
1. Enter system view.
2. Enter public network
IGMP view or VPN
instance IGMP view.
3. Configure an IGMP SSM
mapping.

Configuring IGMP proxying
