10.2 MLD Snooping
MLD Snooping
Multicast Listener Discovery（MLD）snooping is applied for efficient distribution of IPv6 multicast
data to clients and routers in a Layer 2 network. With MLD snooping, IPv6 multicast data is
selectively forwarded to a list of ports that want to receive the data, instead of being flooded to all
ports in a VLAN. The list is constructed and maintained by snooping IPv6 multicast control packets.
MLD snooping performs a similar function in IPv6 as IGMP snooping in IPv4.
