3) Verify the configuration
Carry out the display mld interface command to display the MLD configuration and running
information on each switch interface. Example:
# Display MLD information on VLAN-interface 200 of Switch B.
[SwitchB] display mld interface vlan-interface 200
Vlan-interface200(FE80::200:5EFF:FE66:5100):
MLD is enabled
Current MLD version is 1
Value of query interval for MLD(in seconds): 125
Value of other querier present interval for MLD(in seconds): 255
Value of maximum query response time for MLD(in seconds): 10
Querier for MLD: FE80::200:5EFF:FE66:5100 (this router)

MLD SSM Mapping Configuration Example
Network requirements
z The IPv6 PIM-SM domain applies both the ASM model and SSM model for IPv6 multicast delivery.
Switch D’s VLAN-interface 104 serves as the C-BSR and C-RP. The SSM group range is
FF3E::/64.
z MLDv2 runs on Switch D’s VLAN-interface 400. The receiver host runs MLDv1, and does not
support MLDv2. Therefore, the Receiver host cannot specify expected multicast sources in its
membership reports.
z Source 1, Source 2, and Source 3 send IPv6 multicast packets to multicast groups in the IPv6
SSM group range. It is required to configure the MLD SSM mapping feature on Switch D so that
the receiver host will receive IPv6 multicast data from Source 1 and Source 3 only.
