IGMP/MLD
13.1 IGMP/MLD Overview
Multicast delivers IP packets to a group of hosts on the network defined by multicast groups.
Membership to these multicast groups are established using IGMP/MLD.
Use the
IGMP/MLD
screen to configure IGMP/MLD group settings.
13.1.1 What You Need To Know
Multicast and IGMP
See
for more information.
Multicast Listener Discovery (MLD)
The Multicast Listener Discovery (MLD) protocol (defined in RFC 2710) is derived from IPv4's
Internet
Group Management Protocol version 2 (IGMPv2). MLD uses ICMPv6 message types, rather
than IGMP message types. MLDv1 is equivalent to IGMPv2 and MLDv2 is equivalent to IGMPv3.
• MLD allows an IPv6 switch or router to discover the presence of MLD hosts who wish to receive
multicast packets and the IP addresses of multicast groups the hosts want to join on its network.
• MLD snooping and MLD proxy are analogous to IGMP snooping and IGMP proxy in IPv4.
• MLD filtering controls which multicast groups a port can join.
• An MLD Report message is equivalent to an IGMP Report message, and a MLD Done message is
equivalent to an IGMP Leave message.
IGMP Fast Leave
When a host leaves a multicast group (224.1.1.1), it sends an IGMP leave message to inform all routers
(224.0.0.2) in the multicast group. When a router receives the leave message, it sends a specific query
message to all multicast group (224.1.1.1) members to check if any other hosts are still in the group. Then
the router deletes the host’s information.
With the IGMP fast leave feature enabled, the router removes the host’s information from the group
member list once it receives a leave message from a host and the fast leave timer expires.
