Make sure that the other querier present interval is greater than the MLD query interval; otherwise
the MLD querier may frequently change.
Make sure that the MLD query interval is greater than the maximum response delay for MLD

Configuring MLD SSM Mapping

Due to some possible restrictions, some receiver hosts on an SSM network may run MLDv1. To provide
SSM service support for these receiver hosts, you need to configure the MLD SSM mapping feature on
the last hop router.

Configuration Prerequisites

Before configuring the MLD SSM mapping feature, complete the following tasks:
Configure any 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

Follow these steps to enable the MLD SSM mapping feature:
To do...
Enter system view
Enter interface view
