Multicast Listener Discovery

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 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.

Several operating system support MLDv2:

  • Windows Vista and later
  • FreeBSD since release 8.0
  • The Linux kernel since 2.5.68

Famous quotes containing the words listener and/or discovery:

    “Be a listener only, keep within yourself, and endeavor to establish with yourself the habit of silence, especially in politics.”
    —Thomas Jefferson (1743–1826)

    “That the discovery of this great truth, which lies so near and obvious to the mind, should be attained to by the reason of so very few, is a sad instance of the stupidity and inattention of men, who, though they are surrounded with such clear manifestations of the Deity, are yet so little affected by them, that they seem as it were blinded with excess of light.”
    —George Berkeley (1685–1753)
