Multicast Listener Discovery (MLD) is a component of the Internet Protocol Version 6 (IPv6) suite. MLD is used by IPv6 routers for discovering multicast listeners on a directly attached link, much like Internet Group Management Protocol (IGMP) is used in IPv4. The protocol is embedded in ICMPv6 instead of using a separate protocol. MLDv1 is similar to IGMPv2REFERENCE FOR RFC2710 IS NOT DEFINED YET. You are invited to add it here. and MLDv2 similar to IGMPv3.REFERENCE FOR RFC3810 IS NOT DEFINED YET. You are invited to add it here.
Protocol
The following ICMPv6 message types are used:
ICMPv6 message type values[1] Message Type value Multicast Listener Query 130 MLDv1 Multicast Listener Report 131 MLDv2 Multicast Listener Report 143 Multicast Listener Done 132
Support
Several operating systems support MLDv2:
- Windows Vista and later[2]
- FreeBSD since release 8.0[3]
- The Linux kernel since 2.5.68[4]
- macOS[5]
