A method of hybrid route discovery in a mesh network is described. The method comprises the optional designation of a root node of the mesh network and formatting a route request message at an originating mesh point, where the route request messages include a hop limit parameter. If a root node has been configured, the route request is responded to with a message that describes the route to the root. If a direct route between two nodes is required, the route request message is broadcast from the originating mesh point, and the hop limit parameter limits the number of times the route request message will be forwarded. The originating mesh point receives a unicast route reply message from a neighboring mesh point, after the neighboring mesh point received the route request message. Finally, a route connecting the originating mesh point and the destination mesh point is established.
