NOTE:
The MLD fast-leave processing configuration is effective on Layer 3 interfaces other than VLAN interfaces,
including Layer 3 Ethernet ports, Layer 3 aggregate interfaces, and Tunnel interfaces.
Enabling the MLD host tracking function
With the MLD host tracking function, the switch can record the information of the member hosts that are
receiving IPv6 multicast traffic, including the host IPv6 address, running duration, and timeout time. You
can monitor and manage the member hosts according to the recorded information.

Configuring MLD SSM mapping
Due to some possible restrictions, some receiver hosts on an SSM network might 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 you configure the MLD SSM mapping feature, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain can be interoperable at the network layer
• Configure MLD basic functions
