OSPF
OSPF (Open Shortest Path First) is a standard way computer networks communicate and share information about the best paths for data to travel. Think of it like a GPS system for computer networks - it helps data find the fastest and most reliable route from one point to another. Network professionals use OSPF to make sure large company networks run smoothly and efficiently. When you see OSPF mentioned in a resume, it typically means the candidate has experience with setting up and managing enterprise-level networks. This skill is often mentioned alongside other routing protocols like BGP or EIGRP.

Example Interview Questions
Senior Level Questions
Q: How would you design an OSPF network for a large enterprise with multiple locations?
Expected Answer: A strong answer should discuss planning network areas, considering redundancy, managing traffic between locations, and ensuring network stability. They should mention real-world examples from their experience.
Q: How do you troubleshoot OSPF routing problems in a production environment?
Expected Answer: Look for methodical approaches to problem-solving, mentioning tools they use, and how they minimize network disruption while fixing issues. They should emphasize the importance of documentation and change management.
Mid Level Questions
Q: What are OSPF areas and why are they important?
Expected Answer: Should explain that areas help organize large networks into manageable sections, making the network more stable and easier to maintain, using simple terms and practical examples.
Q: How do you ensure OSPF network security?
Expected Answer: Should discuss basic security measures like authentication between routers, protecting against unauthorized access, and maintaining network stability.
Junior Level Questions
Q: Can you explain what OSPF does in simple terms?
Expected Answer: Should be able to explain that OSPF helps routers share information about the best paths for network traffic, similar to how a GPS finds the best route.
Q: What basic OSPF configuration tasks have you performed?
Expected Answer: Should be able to describe basic setup tasks like enabling OSPF on a router, configuring basic networks, and checking if connections are working.
