Changing an RPF route
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, the receiver can receive the multicast data from the source through the path: Router
A to Router B, which is the same as the unicast route.
Perform the following configuration so that the receiver can receive the multicast data from the source
through the path: Router A to Router C to Router B, which is different from the unicast route.
