5.8 MLD Snooping Configuration

MLD Snooping Overview
Corresponding to the IGMP protocol, MLD is a multicast management protocol in IPv6
environment. MLD v1/v2 is supported.
It is impossible to use a multicast address as a source address in a packet, so a switch
cannot learn the multicast address. When receiving a multicast message, a switch
broadcasts the message on all ports in the same VLAN. If no measure is taken, unwanted
multicast messages may be spread to each node of the network, causing a great waste
of network bandwidth resource.
Multicast Listener Discovery (MLD) snooping monitors MLD protocol communication
between a host and a router. In this way, a multicast message is sent to the ports in the
multicast forwarding table instead of all ports. This limits multicast message spread on
LAN switches, reduces network bandwidth waste, and enhances switch usage.
Configuring MLD Snooping
The MLD snooping configuration includes the following commands:
