Multicast listener done
The Multicast Listener Done message is sent by a host in a specific multicast group to the multicast router, to signal the router that there may not be any further group members on the local subnet. When the router receives a Done message, it queries the subnet for further group members by sending a Multicast Listener Query message.
The Multicast Listener Report message is equivalent to an IGMPv2 Leave Group message. It is ICMPv6 message type 132.
