Chapter 7 Firewall for FortiOS 5.0 : Multicast forwarding : Multicast routing examples : Example PIM configuration that uses BSR to find the RP
  
Example PIM configuration that uses BSR to find the RP
This example shows how to configure a multicast routing network for a network consisting of four FortiGate-500A units (FortiGate-500A_1 to FortiGate-550A_4, see Figure 180). A multicast sender is connected to FortiGate-500A_2. FortiGate-500A_2 forwards multicast packets in two directions to reach Receiver 1 and Receiver 2.
The configuration uses a Boot Start Router (BSR) to find the Rendezvous Points (RPs) instead of using static RPs. Under interface configuration, the loopback interface lo0 must join the 236.1.1.1 group (source).
