How to Configure OSPF on FortiGate & Cisco L3 Switch | Full GNS3 Lab Guide
In this video, I demonstrate how to configure OSPF routing between a FortiGate firewall and a Cisco Layer 3 switch using GNS3.
This lab shows real-world dynamic routing integration commonly used in enterprise. You will learn how routers and firewalls exchange routes automatically using OSPF to achieve efficient internal network communication.
📚 What You’ll Learn:
✅ OSPF configuration on FortiGate
✅ OSPF configuration on Cisco L3 switch
✅ Route exchange and troubleshooting
💻 Tools Used:
• GNS3 Network Simulator
• FortiGate VM
• Cisco Layer 3 Switch
• VPCS
This setup is perfect for students, network engineers, and homelab enthusiasts preparing for networking certifications or improving real-world routing skills.
By the end of this video, you will understand how to configure OSPF routing between a FortiGate firewall and a Cisco Layer 3 switch.
