Examples for configuring static multicast routes and multicast load splitting are provided.

9.8.1 Example for Changing Static Multicast Routes to RPF Routes

Networking Requirements

As shown in Figure 9-1, PIM-DM runs on the network and all the Switches support multicast.

The receiver can receive information from the multicast source. Switch A, Switch B, and Switch

C run OSPF. You need to configure a static multicast route to make the multicast path from the

source to the receiver different from the unicast path from the source to the receiver.
