FortiGate HA + FortiSwitch MCLAG Configuration Guide | 2 Firewalls + 2 Switches

In this video, I walk through a full FortiGate HA and FortiSwitch MCLAG lab setup using 2 FortiGate firewalls and 2 FortiSwitches.

This is a great design for building a more resilient network with firewall redundancy, switch redundancy, and reduced single points of failure. I go through the overall topology, key concepts, and the configuration process so you can understand how these pieces fit together in a real deployment.

In the lab, I cover:
- FortiGate HA configuration
- FortiSwitch MCLAG configuration
- How the firewalls and switches work together
- Redundant design considerations
- Management Reservation Interfaces
- Tips for labbing and deployment planning

This setup is useful for anyone working with Fortinet firewalls, FortiSwitches, campus networks, branch deployments, or data center edge designs.

If you’re learning Fortinet or building out a production-ready design, this should help you understand the basics of HA + MCLAG.
