OSPF (Open Shortest Path First) is a link-state routing protocol that dynamically calculates the shortest path between routers using Dijkstra’s algorithm. It operates within an autonomous system (AS) and supports hierarchical network design through the use of areas, reducing routing overhead and improving scalability. OSPF exchanges link-state advertisements (LSAs) to maintain a synchronized and loop-free topology. It supports equal-cost multipath (ECMP), fast convergence, and features like authentication, route summarization, and stub areas for optimized performance. OSPF runs directly over IP (protocol number 89) and is widely used in enterprise and service provider networks for its efficiency and flexibility.
