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)

    The discovery of Pennsylvania’s coal and iron was the deathblow to Allaire. The works were moved to Pennsylvania so hurriedly that for years pianos and the larger pieces of furniture stood in the deserted houses.
    —For the State of New Jersey, U.S. public relief program (1935-1943)
