Example FortiGate PIM-SM configuration using a static RP
The example Protocol Independent Multicast Sparse Mode (PIM-SM) configuration shown below has been tested for multicast interoperability using PIM-SM between Cisco 3750 switches running 12.2 and a FortiGate-800 running FortiOS v3.0 MR5 patch 1. In this configuration, the receiver receives the multicast stream when it joins the group 233.254.200.1.
Example FortiGate PIM-SM topology
The configuration uses a statically configured rendezvous point (RP) which resides on the Cisco_3750_1. Using a bootstrap router (BSR) was not tested in this example. See “Example PIM configuration that uses BSR to find the RP” for an example that uses a BSR.
Configuration steps
The following procedures show how to configure the multicast configuration settings for the devices in the example configuration.
- Cisco_3750_1 router configuration
- Cisco_3750_2 router configuration
- To configure the FortiGate-800 unit
- Cisco_3750_3 router configuration
