A relay device includes a processor that executes a procedure. The procedure includes detecting a change in a first communication state between a local device and a first relay device that is arranged in a stage preceding or succeeding the local device and connected to the local device with a logical path, obtaining, from a second relay device for relaying a logical path different from the logical path relayed by the local device, a second communication state between the second relay device and a third relay device that is arranged in a stage preceding or succeeding the second relay device and connected to the second relay device with a logical path, and enabling a logical path between the local device and the second relay device according to a combination of the first and the second communication states when the change in the first communication state is detected.
