Configuring MLD SSM mapping
For some certain restrictions, some receiver hosts on an SSM network might run MLDv1. To provide SSM
service support for these receiver hosts, configure the MLD SSM mapping feature on the last-hop router.
Configuration prerequisites
Before you configure the MLD SSM mapping feature, complete the following tasks:
• Configure an IPv6 unicast routing protocol so that all devices in the domain can be interoperable
at the network layer.
• Configure basic MLD functions.
