TMP

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 IGMPv2Vorlage:Ref RFC and MLDv2 similar to IGMPv3.Vorlage:Ref RFC

Protocol

The following ICMPv6 message types are used:

ICMPv6 message type values

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
• FreeBSD since release 8.0
• The Linux kernel since 2.5.68
• macOS
