Route data acquisition method, layer 2 device, carrier net interior position and route data collector

摘要

The response packet where this route data acquisition method, when the transmission original device, the response possible layer 2 device or the carrier net interior position, the above-mentioned required packet is received in step and the required packet which transmit the required packet which that it replies to the transmission original device, requires the response packet which includes the particular layer 2 device or the specified setting data of the carrier net interior position vis-a-vis at least the layer 2 device and the carrier net interior position of sutra road surface to the address device, reads out the specified setting data which is housed in the storage unit of the layer 2 device, includes the particular specified setting dataAs it transmits to the transmission original device, when step and the transmission original device which output the above-mentioned required packet to the address device address, the response packet is received, it includes with the indicatory step which indicates the specified setting data which is included in the particular response packet in the display. If it makes this way, the layer 2 device and it is produced, to receive the specified setting data from also the carrier net interior position, reaches the point where it can examine the device of sutra road surface.
