Network topology of the application presented in Fig. 1. Each box represents the node in the network. The shaded nodes are new recipients. The dashed lines show possible reverse routes, while the solid lines show the discovered route. 1 Node N1 receives a low-priority binding request. 2 N1 broadcasts a route discovery message, N2 and Nx receive it. 3 N2 and Nx are not the intended destination. N2 and Nx make an entry in their node and forwards the request to their neighbours. 4 The intended destination N3 has been found. N3 sends out a route reply message along the reversed path of the request. This route reply message configures all the intermediate nodes and the source node
