Multicast Listener Discovery version 1 (MLDv1) is a protocol used by IPv6 routers to learn about the multicast group membership of neighboring IPv6 hosts on a network. MLDv1 messages are sent between routers and hosts to signal membership or non-membership of a multicast group.

The IGMP (Internet Group Management Protocol) is a protocol used by IPv4 routers to learn about the multicast group membership of neighboring IPv4 hosts on a network. The IGMP Leave message is used by a host to signal to the router that it is no longer interested in receiving traffic for a particular multicast group.

To answer the question, the MLDv1 message that is equivalent to the IGMP Leave message is the "Done" message, which is sent by a host to signal to the router that it is leaving a multicast group. This is similar to the IGMP Leave message, which signals that a host is no longer interested in receiving traffic for a particular multicast group.

The other options are incorrect:

  • "Finish" is not a valid MLDv1 message.
  • "Leave" is not a valid MLDv1 message. It is similar to the IGMP Leave message but is not used in MLDv1.
  • "Report" is an MLDv1 message sent by a host to signal to the router that it is interested in receiving traffic for a particular multicast group. It is similar to the IGMP Join message.
