Each node is required to know the topology of the network within its routing zone only. Thus, nodes are updated about topological changes only witin their routing zones. Thus, in spite of the fact that a network can be quite large, the updates are only locally propagated. Since for radius greater than one, the routing zones heavily overlap, the routing tends to be extremely robust. The routes within the network are specified as a sequence of nodes, separated by approximately the zone radius.
