Networks break when they aren’t designed for failure.
This 6-week course teaches you how to think like a network architect — not just configure devices. You’ll learn what, why, and how at each step, from subnet design to VxLAN troubleshooting.
You’ll Learn To:
Design redundant and scalable subnet schemes (RFC6598/RFC1918)
Deploy OSPF and BFD for sub-second failover
Extend Layer 2 networks across data centers with VxLAN
Tune MTU, cost, and routes for optimal performance
Troubleshoot like a pro using ROMON and firewall analytics
