4.7.4 (Optional) Enabling the MLD Snooping Module to Respond
to Changes of the Layer 2 Network Topology
Context
To enable the MLD snooping module to respond to changes of the Layer 2 network topology,
do as follows on the S2700.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
mld-snooping send-query enable
The MLD snooping module of the S2700 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 S2700 is
FE80::.
Step 3
topology, it sends an MLD General Query message to the downstream S2700 when receiving a
Topology Change message. Then the downstream S2700 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 S2700 and its downstream S2700 can learn
the new multicast forwarding entry. This function enables the S2700 to forward multicast data
correctly after the Layer 2 topology changes.
