Detailed explanation-1: -Routing protocols are mechansims by which routing information is exchanged between routers so that routing decisions can be made. In the Internet, there are three types of routing protocols commonly used. They are: distance vector, link state, and path vector.
Detailed explanation-2: -The information exchange enables all participating routers to establish their link-state database. OSPF uses a cost metric that represents the status of the link and the bandwidth of the interface in an algorithm to determine the best route to a destination.
Detailed explanation-3: -The OSPF protocol is a link-state routing protocol, which means that the routers exchange topology information with their nearest neighbors. The topology information is flooded throughout the AS, so that every router within the AS has a complete picture of the topology of the AS.
