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 and MLDv2 similar to IGMPv3. The protocol is described in RFC 3810 which has been updated by RFC 4604.
Protocol
The ICMPv6 messages use type 143.[1]
Support
Several operating system support MLDv2:
- Windows Vista and later[2]
- FreeBSD since release 8.0[3]
- The Linux kernel since 2.5.68[4]
