25.1.6 MLD Messages
A multicast router or switch periodically sends general queries to MLD hosts to update the multicast
forwarding table. When an MLD host wants to join a multicast group, it sends an MLD Report
message for that address.
An MLD Done message is similar to an IGMP Leave message. When an MLD host wants to leave a
multicast group, it can send a Done message to the router or switch. If the leave mode is not set to
Immediate, the router or switch sends a group-specific query to the port on which the Done
message is received to determine if other devices connected to this port should remain in the
group.
