Patent ID: 8908670

Claim:
A method for generating an extended route request message for route discovery of a route from a connection source node of an IEEE 802 connection to a connection destination node of an IEEE 802 connection including a mesh path in a mesh network with a mesh source node of the mesh path and a mesh destination node of the mesh path, comprising: determining whether the connection source node is inside or outside the mesh network; generating the extended route request message to include one source address of the mesh source node and a flag set to indicate that the extended route request message covers the one source address, if the connection source node is located inside the mesh network; and generating the extended route request message to include two source addresses covering (a) the source address of the mesh source node and (b) the source address of the connection source node and the flag set to indicate that the extended route request message covers the two source addresses, if the connection source node is located outside the mesh network, and wherein the flag is selectively set depending on a location of the connection source node relative to the mesh network affecting generation of the extended route request message.
