1. A relay device installed in a vehicle, the relay device comprising:
a detection unit configured to detect a new function unit being a function unit that is newly added to a network including an existing function unit being one or a plurality of function units;
a relay unit configured to relay a frame between the function units; and
an acquisition unit configured to acquire, from the frame, relayed by the relay unit, between the new function unit detected by the detection unit and the existing function unit, function unit information that includes information regarding a network configuration of a layer of a lower order than an application layer, the function unit information being of at least one of the new function unit and the existing function unit, wherein
the function unit information includes at least one of:
information that allows recognition of a topology of a new network and the specifications of a hardware device in the new network, the new network being the network that further includes the new function unit;
a restriction regarding disposition of an application in the hardware device in the new network; and
a restriction of a communication method in the new network.
