Configuring MLD snooping
Overview
MLD snooping runs on a Layer 2 switch as an IPv6 multicast constraining mechanism to improve
multicast forwarding efficiency. It creates Layer 2 multicast forwarding entries from MLD messages
that are exchanged between the hosts and the router.
As shown in
, when MLD snooping is not enabled, the Layer 2 switch floods IPv6 multicast
packets to all hosts. When MLD snooping is enabled, the Layer 2 switch forwards multicast packets
of known IPv6 multicast groups to only the receivers of the multicast groups.

Basic MLD snooping concepts
This section lists the basic MLD snooping concepts.
MLD snooping related ports
As shown in
, MLD snooping runs on Switch A and Switch B. Host A and Host C are
receivers in an IPv6 multicast group.
