🦑 Troubleshooting OSPFv2 Neighbor Adjacencies Made Easy! 🛠
Are your OSPFv2 neighbors stuck in states like Init, 2-Way, or ExStart? Troubleshooting OSPF can be tricky, but with the right approach, you can resolve issues quickly! Here's a checklist to help:

✅ 1. Check Network Types
Ensure both devices are on the same network type (Broadcast, Point-to-Point, Non-Broadcast, etc.). A mismatch could lead to adjacency issues.
✅ 2. Verify Subnet Masks
Neighbors must share the same subnet. Run show ip ospf interface to confirm.
✅ 3. Confirm Hello and Dead Timers
Default timers should match. Use show ip ospf neighbor to check compatibility.
✅ 4. Authentication Configurations
Is OSPF authentication enabled? Double-check the keys and methods (Plaintext/MD5).
✅ 5. MTU Mismatch
A mismatch in MTU can cause neighbors to get stuck in ExStart. Use ip ospf mtu-ignore if necessary.
✅ 6. Router IDs
Each router must have a unique Router ID. Conflicts can disrupt adjacencies.
✅ 7. Passive Interfaces
Is OSPF accidentally configured as passive on the neighbor-facing interface? Check your configs!
✅ 8. Access-Lists or Firewalls
Ensure UDP packets on ports 520 and 89 aren't blocked by ACLs or firewalls.
Troubleshooting OSPF is all about systematic checks and leveraging show/debug commands. Here's my golden rule: Start from Layer 1 and move up!
💡 What’s your go-to step when troubleshooting OSPF adjacencies?

Pentesting is primarily concerned with identifying and exploiting vulnerabilities within a specific target system, striving to uncover as many weaknesses as possible.
This process aids in shoring up an organization's defenses by pinpointing areas of vulnerability.

On the other hand, a red team engagement shifts its focus. Instead of merely finding vulnerabilities, it aims to assess an organization's defensive capabilities by simulating real-world attacks.
The goal is to evaluate how well the organization can detect and respond to these simulated threat actors.
