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 i nto th e co rrect IPv6 m ulticast tab le, and begins th e pro cess of forwarding m ulticast traffi c t o that port. This ent ry i n th e
multicast ro uting tab le reco rds th e port, t he VLAN ID, and t he ass ociated m ulticast IPv6 m ulticast gr oup a ddress, an d t hen
considers this port to be an active listening port. The active listening ports are the only ones to receive multicast group data.
