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 IGMPv2[1] and MLDv2 similar to IGMPv3.[2]
Protocol
The following ICMPv6 message types are used:
ICMPv6 message type values[2] 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[3]
- FreeBSD since release 8.0[4]
- The Linux kernel since 2.5.68[5]
- macOS[6]
