MLD Snooping Settings
Multicast Listener Discovery (MLD) Snooping is an IPv6 function used similarly to IGMP snooping in
IPv4. It is used to discover ports on a VLAN that are requesting multicast data. Instead of flooding all
ports on a selected VLAN with multicast traffic, MLD snooping will only forward multicast data to
ports that wish to receive this data through the use of queries and reports produced by the requesting
ports and the source of the multicast traffic.
MLD snooping is accomplished through the examination of the layer 3 part of an MLD control packet
transferred between end nodes and a MLD router. When the Switch discovers that this route is
requesting multicast traffic, it adds the port directly attached to it into the correct IPv6 multicast table,
and begins the process of forwarding multicast traffic to that port. This entry in the multicast routing
table records the port, the VLAN ID and the associated multicast IPv6 multicast group address and then
considers this port to be a active listening port. The active listening ports are the only ones to receive
multicast group data.
The Switch supports both MLD Snooping version 1 and MLD version 2.
MLD Control Messages
If implementing MLD snooping version 1, three types of messages are transferred between devices.
These three messages are all defined by three ICMPv6 packet headers, labeled 130, 131, and 132.
1 Multicast Listener Query, Version 1 – Similar to the IGMPv2 Host Membership Query for IPv4, and
labeled as 130 in the ICMPv6 packet header, this message is sent by the router to ask if any link is
