1. A method, comprising: transmitting, from a source node, one or more route request (RREQ) messages toward a destination node of a reactive routing computer network, each RREQ message having an indication that it should be transmitted all the way to the destination node; recording, at one or more intermediate nodes, a traversed path of the RREQ message within the RREQ message; receiving one or more of the RREQ messages at the destination node during a configured time period after receiving a first RREQ message at the destination node; and determining two or more routes from the source node to the destination node based on the received RREQ message at the destination node and one or more path selection criteria.
