MLD Snooping Application

MLD Snooping Application

Networking Description

As shown in Figure 11-18, a multicast source exists on an IPv6 PIM network and provides multicast video services for users on the LAN. Some users such as HostA and HostC on the LAN want to receive video data in multicast mode. To prevent multicast data from being broadcast on the LAN, configure MLD snooping on Layer 2 multicast devices to accurately forward multicast data on the Layer 2 network, which prevents bandwidth waste and network information leakage.

Figure 11-18 MLD snooping networking

Deployed Features

You can deploy the following features to accurately forward multicast data on the network shown in Figure 11-18:

  • IPv6 PIM and MLD on the Layer 3 multicast device Router to route multicast data to user segments.
  • MLD snooping on the Layer 2 device Switch so that Switch can set up and maintain a Layer 2 multicast forwarding table to forward multicast data to specified users.
  • MLD snooping proxy after configuring MLD snooping on Switch to release Router from processing a large number of MLD messages.
