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