Understanding the OSPF Routing Protocol in Less Than 13 Minutes!!!!
The Open Shortest Path First (OSPF) routing protocol is a routing protocol used primarily in autonomous local area networks (AS). It is an interior routing protocol designed for use in a local area network environment, rather than for internet-wide routing. OSPF is a link-state routing protocol, meaning that OSPF routers exchange routing information with their neighbors to maintain a complete network map.
The OSPF protocol uses shortest path calculation algorithms to determine the best route for sending data packets to their destination. It uses a cost system to evaluate each possible route, using criteria such as the available bandwidth on each link or the number of hops required to reach the destination. The least-cost path is selected as the best route.
