Changing an RPF route

Network requirements
As shown in
•
PIM-DM runs on the network.
•
All switches on the network support multicast.
•
Switch A, Switch B and Switch C run OSPF.
•
Typically, the receiver host can receive the multicast data from Source through the path: Switch
A to Switch B, which is the same as the unicast route.
Configure the switches so that the multicast data from Source travels to the receiver through the
path: Switch A to Switch C to Switch B. This is different from the unicast route.
