Integrate Fortigate in Cisco Network using EIGRP



In my network i have a Cisco Switch connected to Cisco VSS Switchs (Core) using EIGRP routing protocol. 

I want to integrate a Firewall ( Fortigate) between these two switchs and i can not change the routing protocol since i have many routes already configured in VSS.

What is the perfect methode to integrate the Fortigate in this Network ?

You should have considered the routing protocol before getting a new FW. Only way to put router/FW that doesn't support EIGRP like FortiGate in to Cisco network with EIGRP is finding a common protocol like OSPF or BGP that the FGT supports then redistribute routes between EIGRP and OSPF/BGP at the Cisco VSS switch like below.
There should be many more documents available publicly. If any problems, you can ask them in the Cisco Community.



Hi @Atef_21 ,


FortiGate does not support EIGRP routing protocol. You may find some useful information on the following links:

Hello @fricci_FTNT / @Toshi_Esumi ,

I would to thank you for your responses, but the problem here that i have many routes configured in my switchs and i cannot change the routing protocol because it will be very critical. So i'm asking here if there are some features in Fortigate to solve this case.

Why not run OSPF on your switches and then re-distribute EIRGP into OSPF.  Then run OSPF on the gate.
