12.3 MLD Snooping
MLD snooping is the abbreviation of multicast Listener Discovery snooping. It is an
IPv6 Multicast constraint mechanism running on layer 2 devices, which is used to manage
and control IPv6 Multicast Groups.
The second layer device running MLD snooping establishes a mapping relationship
between port and MAC multicast address by analyzing the received MLD message, and
forwards IPv6 multicast data according to the mapping relationship
As shown in the figure below, when the layer 2 device does not run MLD snooping,
the IPv6 multicast data packets are broadcast at layer 2; when the layer 2 device runs MLD
snooping, the multicast data packets of known IPv6 Multicast groups will not be broadcast at
layer 2, but will be multicast to the designated receivers at layer 2.
MLD snooping can only forward information to the receivers in need through layer 2
multicast, which can bring the following benefits:
● Reduce the broadcast packets in the layer 2 network and save the network
bandwidth.
● Enhance the security of IPv6 Multicast information.
● It is convenient to charge each host separately.
