Open Shortest Path First (OSPF) (โปรโตคอลเส้นทางสั้นที่สุดแบบเปิด (OSPF)) Hard Skill
Open Shortest Path First (OSPF) is a dynamic link-state routing protocol used in Internet Protocol (IP) networks to find the best path for data packets by calculating the shortest path tree. It enables efficient and scalable routing by sharing topology information within a single autonomous system.
Expertise Level
Level 1
Basic
1. Understands the fundamental concepts of OSPF and its role in IP networks.
2. Can identify OSPF router types and basic packet types (Hello, LSAs).
3. Familiar with OSPF areas and how the protocol maintains routing tables.
Level 2
Intermediate
1. Can configure and troubleshoot OSPF on routers in a single area network.
2. Understands OSPF neighbor relationships and state transitions.
3. Able to analyze OSPF route advertisements and perform basic optimizations.
Level 3
Advanced
1. Designs and manages complex OSPF networks with multiple areas and routers.
2. Optimizes OSPF configurations for scalability, security, and performance.
3. Troubleshoots advanced issues such as LSDB inconsistencies, route flapping, and inter-area routing problems.
