An algorithm for routing a message along the shortest path between a pair of processors in 2-jump circulant (undirected double fixed step) networks is given. The algorithm requires ?(d) time for preprocessing, and ` = O(d) routing steps, where ` is the distance between the processors and d is the diameter of the network.
