Networking Requirements
As shown in Figure 6-2, PIM-DM runs on the network and all S9300 support multicast. The
receiver can receive information from the multicast source Source1. S9300-B and S9300-C run
OSPF. No unicast route is available between S9300-A and S9300-B. You need to use a multicast
static route to enable the receiver to receive information sent by Source2.

Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the IP addresses of interfaces and the unicast routing protocol on each S9300.
2. Enable the multicast function on all routers, PIM-SM on all interfaces, and IGMP on the
interfaces connected to hosts.
