6.16 Configuration Examples
Configuration examples are provided to show how to construct a basic PIM-SM network and
configure basic functions of PIM-SM.
6.16.1 Example for Configuring the PIM-SM Network
Networking Requirements
As shown in Figure 6-2, multicast is deployed on the network of an Internet Service Provider
(ISP). The Interior Gateway Protocol (IGP) is deployed on the network. The unicast routing
routes work normally and are connected to the Internet. The routers on the network need to be
configured properly so that hosts can receive the video on demand (VOD) in multicast mode.
