Research on link-state routing and ospf configuration on cisco network devices

Abstract

In the Link-State routing protocol, each router acquires an entire database of the state of neighbor links in the network, a process called network learning. Using this information, each router builds a complete link states database and calculates the best route for any given data packet, then every router in the internet connection has the same information about internet connection. Link-state routing uses the concept of areas. Network administrators can divide the routing domain into separate areas to help quickly converge, reduce the possibility of creating loops in the network, control traffic, quickly update routing tables. Based on theory, the author presents OSPF configuration content on a specific network model.
