Multicast Listener Discovery

Multicast Listener Discovery - Beschreibung

Beschreibung

‚‘'Multicast Listener Discovery'‚‘ (‚‘'MLD'‚‘) ist eine Komponente der Internet Protocol Version 6 (IPv6)-Suite. MLD wird von IPv6-Routern verwendet, um Multicast-Empfänger auf einer direkt verbundenen Verbindung zu erkennen, ähnlich wie Internet Group Management Protocol (IGMP) in IPv4 verwendet wird. Das Protokoll ist in ICMPv6 eingebettet, anstatt ein separates Protokoll zu verwenden. ‚‘'MLDv1'‚‘ ähnelt IGMPv2 und ‚‘'MLDv2'‚‘ ähnelt IGMPv3.

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.

Protocol

ICMPv6 messages
