Which type of routing protocol maintains a complete map of the network and calculates the shortest path to each node using algorithms such as Dijkstra's?
Link-state routing protocols maintain a complete map of the network by having each router maintain a database of the entire topology. They use algorithms such as Dijkstra's Shortest Path First (SPF) algorithm to compute the shortest path to each node in the network. Distance vector protocols, on the other hand, rely on distance vectors from neighbors and do not maintain a complete map of the network. Hybrid protocols combine aspects of both link-state and distance vector protocols.
