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