Abstract
A relay device that includes a processor that is configured to: monitor a state of the in-vehicle network; perform update processing of the correspondence information; switch between a stopped state in which the update processing is stopped and an execution state in which the update processing is executed, and to switch from the stopped state to the execution state when a change in the state of the in-vehicle network is detected; and save, in the memory, the correspondence information on which the update processing is performed in the execution state as the correspondence information to be used for the relay processing in the stopped state, when the processor switches from the execution state to the stopped state.
