The system view is displayed.
Step 2 Run:
vlan vlan-id
The VLAN view is displayed.
Step 3 Run:
mld-snooping prompt-leave [ group-policy acl-number ]
Prompt leave is enabled for interfaces in the VLAN.
NOTE
By default, no interface is allowed to promptly leave a multicast group.
If group-policy acl-number is not specified in step 3, the S7700 deletes the forwarding entry of a member
interface immediately when receiving a Done message from the interface.

11.5.3 Checking the Configuration
Procedure
Step 1 Run the display mld-snooping [ vlan vlan-id ] [ configuration ] command to check the
configuration of MLD snooping in a VLAN.
If the configuration is successful, you can find that the prompt leave function is configured
correctly in the VLAN.

11.6 Configuring the MLD Snooping Querier
This section describes how to configure the MLD snooping querier.
11.6.1 Establishing the Configuration Task
Applicable Environment
If a network does not have a Layer 3 multicast device, the MLD querier functions are unavailable
because the Layer 2 devices do not support MLD. To solve this problem, you can enable the
MLD snooping querier on the Layer 2 devices so that the Layer 2 devices can create and maintain
the IPv6 multicast forwarding entries at the data link layer. In this way, the IPv6 multicast data
can be forwarded at the data link layer.
Pre-configuration Tasks
Before configuring the MLD snooping querier on the VLAN, complete the following task:
l Enabling the MLD snooping function on the VLAN
Data Preparation
To configure the MLD snooping querier in a VLAN, you need the following data.
