Network requirements
PIM-DM runs in the network. All routers in the network support multicast. Router A, Router B, and Router
C run OSPF. Typically, Receiver can receive the multicast data from Source through the path Router A to
Router B, which is the same as the unicast route. Receiver can receive the multicast data from Source
through the path: Router A to Router C to Router B, which is different from the unicast route.
