The PIM-SM network implements OSPF to provide unicast routes and establish MSDP
peers between SwitchC and SwitchD. Meanwhile, the Loopback10 interfaces of
SwitchC and SwitchD play the roles of C-BSR and C-RP.

Configuration procedure
1 Configure interface IP addresses and unicast routing protocol on the switches.
In the PIM-SM domain, configure the interface IP addresses on the switches and
interconnect the switches through OSPF. Configure the IP address and mask of each
interface according to Figure 173. The details are omitted here.
2 Enable multicast and configure PIM-SM.
a Enable multicast on SwitchC and enable PIM-SM on all interfaces. The
configuration procedures on other switches are similar to that on SwitchC. The
details are omitted here.

b Configure the same Loopback10 interface address on SwitchC and SwitchD and
configure the locations of C-BSR and C-RP. The configuration procedure on
SwitchD is similar to that on SwitchC. The details are omitted here.
