Routing Protocol Concepts
Generally speaking, most routing protocols used today are based on one of two types of distributed routing algorithms: link-state or distance vector. In the next few sections, we'll discuss the different properties of distance vector and link-state routing algorithms.
Distance Vector Routing Protocols
Distance vector protocols are sometimes referred to as Bellman-Ford protocols, named after the person who invented the algorithm used for calculating the shortest paths[2] and for the people who first described a distributed use of the algorithm[3]. The term distance vector. is derived from the fact that the protocol includes a vector (list) of distances (hop counts or other metrics) associated with each destination ...
