Configure IGMP SSM Mapping
Configuration Conditions
Before configuring the IGMP SSM mapping, first complete the following tasks:
- Configure the network layer address of the interface, making the neighboring node network layer reachable;
- Enable the IGMP protocol.
Configure IGMP SSM Mapping
To provide the PIM-SSM service for the receiver not supporting IGMPv3 in the PIM-SSM network, we can configure the IGMP SSM Mapping function on the device.
The user can configure the IGMP SSM Mapping rule according to the demand of the network receiver. The group member relation report permitted by the rule is converted to the IGMPv3 non-member (IS_EX, TO_EX) relation report, and the multicast source address is the source address specified by the IGMP SSM mapping rule.
