Configure OSPF for interoperability among the switches. Ensure the network-layer
interoperation on the PIM-SM domain and dynamic update of routing information among the
switches through a unicast routing protocol. The detailed configuration steps are omitted here.
2) Enable IP multicast routing, enable PIM-SM on each interface, and enable IGMP and IGMP
SSM mapping on the host-side interface.
# Enable IP multicast routing on Switch D, enable PIM-SM on each interface, and enable
IGMPv3 and IGMP SSM mapping on VLAN-interface 400.

The configuration on Switch B and Switch C is similar to that on Switch A.
3) Configure a C-BSR and a C-RP
# Configure C-BSR and C-RP interfaces on Switch D.

[SwitchD-pim] quit
4) Configure the SSM group range
# Configure the SSM group range 232.1.1.0/24 on Switch D.
[SwitchD] acl number 2000
[SwitchD-acl-basic-2000] rule permit source 232.1.1.0 0.0.0.255
