MLD Snooping
Multicast packets are addressed with multicast MAC addresses, which represent a group of devices, rather
than one unique device. Switches forward multicast frames out of all ports in a VLAN by default, even
though there may be only some interested hosts, which is a waste of bandwidth. MLD Snooping enables
switches to use information in MLD packets to generate a forwarding table that associates ports with
multicast groups so that when they receive multicast frames, they can forward them only to interested
receivers.
