📌 OSPF Multi-Area Configuration Step-by-Step – Fix Routing Issues!

🌐 Struggling with OSPF areas that won’t communicate? In this hands-on lab, we’ll configure multi-area OSPF from scratch and troubleshoot why Router 2 couldn’t see its neighbors. Here’s what you’ll learn:

🔍 Step-by-Step Lab Walkthrough:
✅ The Critical Mistake – Why Router 2 couldn’t ping Router 3 (missing area config!)
✅ ABR Magic – How Router 2 became the Area Border Router linking Area 0 and Area 1
✅ Key Verification Commands:

show ip ospf neighbor (Who’s your OSPF buddy?)

show ip route ospf (Spot those "O IA" inter-area routes)

show ip protocols (Check area assignments)

⚡ Pro Tips:

Why loopback addresses matter for router IDs

How wildcard masks (0.0.255.255) simplify OSPF config

The "O IA" flag in routing tables (your inter-area traffic passport)

🚀 Perfect For:
