In this video, I walk through the design, implementation, and validation of a real-world campus network built in GNS3, inspired by enterprise networking best practices.
This lab demonstrates how a small but security-focused campus can use dual ISP connectivity with BGP, strict routing policy, and firewall-segmented trust zones to achieve stability, control, and scalability.
🔧 What’s covered in this video:
Dual ISP connectivity using BGP (default-route only policy)
Campus segmentation with VLANs (10/20/30/40)
A dedicated DMZ protected by Cisco ASAv
Firewall ACLs, NAT (PAT & Identity NAT) and security zoning
Campus ↔ DMZ traffic control and validation
Real troubleshooting scenarios and fixes
End-to-end testing: routing, NAT, DNS, and internet access
This project reflects real enterprise design decisions, not just textbook labs, and is fully documented for professional and academic use.
