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