I’ve put together a small guide for setting up two Fortigates with failover ospf routing. This example is based on a small lab, but you can easily adapt it to your own environment. This is the scenario: In this scenario we want the 100Mb line to be prioritized. Start of with setting up the two Fortigates with ip-adresses as shown. Also make sure to create firewall rules for traffic from internal to wan1 and wan2 and back (make sure not to enabel NAT). Then you have to enter the following config to enable ospf: On FGT1: config router ospf config area edit 0.0.0.0 next end config network edit 1 set prefix 0.0.0.0 0.0.0.0 next end config ospf-interface edit “wan1” set cost 2 set interface “wan1” next edit “wan2” set interface “wan2” next end config redistribute “connected” end config redistribute “static” end config redistribute “rip” end config redistribute “bgp” end set…

You can review the status from the main page.…
