How does OSPF determine the best path for routing packets in a large network?

Example Concept: OSPF routers exchange link-state advertisements (LSAs) to build a complete topology map of the network. Each router independently calculates the shortest path to every other router using the Dijkstra algorithm. The path with the lowest cumulative cost, determined by the sum of interface costs, is selected as the best route. This process ensures that OSPF can efficiently route packets in large and complex networks by dynamically adapting to changes in topology.
