frequently from one IPv6 multicast group to another, you can enable MLD fast-leave processing on the
MLD querier.
When fast-leave processing is enabled, after receiving an MLD done message from a host, the MLD
querier sends a leave notification to the upstream immediately without first sending MLD
multicast-address-specific queries. In this way, the leave latency is reduced on one hand, and the network
bandwidth is saved on the other hand.

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. The member host information includes the host IPv6 address, running
duration, and timeout time. You can monitor and manage the member hosts according to the recorded
information.
