Huawei quidway s7700 - Optional) Setting the Duration for Suppressing the same MLD Messages; Checking the Configuration

mld-snooping send-query enable
The MLD snooping module of the S7700 is enabled to respond to changes of the Layer 2 network
topology.
Step 3 Run:
mld-snooping send-query source-address ipv6-address
The source IPv6 address of the MLD General Query messages that the MLD snooping module
sends to respond to changes of the Layer 2 network topology is set.
By default, the source IPv6 address of the MLD General Query message sent by the S7700 is
FE80::.
Step 3 is optional. After the S7700 is enabled to respond to changes of the Layer 2 network
topology, it sends an MLD General Query message to the downstream S7700 when receiving a
Topology Change message. Then the downstream S7700 can learn the new router interface.
When a member interface receives the MLD General Query message, the member interface
responds with an MLD Report message. Then the S7700 and its downstream S7700 can learn
the new multicast forwarding entry. This function enables the S7700 to forward multicast data
correctly after the Layer 2 topology changes.
