Summary of MLD Snooping Configuration Tasks
Table 10-3 lists MLD snooping configuration tasks.
Task |
Description |
|---|---|
| Configuring Basic MLD Snooping Functions | On an IPv6 network, when multicast data is forwarded to a Layer 2 multicast device connected to a user network segment, configure MLD snooping on the Layer 2 multicast device to prevent multicast data from being flooded in the broadcast domain and to accurately forward multicast data at Layer 2. After MLD snooping is configured, the Layer 2 multicast device can snoop and analyze MLD messages between multicast users and the upstream router. The Layer 2 multicast device sets up Layer 2 multicast forwarding entries to control forwarding of multicast data. In this way, multicast data is not broadcast on the Layer 2 network. |
| Configuring the MLD Snooping Policy | To filter out multicast messages on a Layer 2 multicast device or limit the range of multicast groups that hosts can join, configure an MLD snooping policy on the Layer 2 multicast device. |
| Configuring Membership Fast-Update | To improve running efficiency of multicast services and user experience, configure quick membership update on a Layer 2 multicast device so that the Layer 2 multicast device quickly updates entries when receiver hosts join or leave a multicast group. |
