Abstract: A single router system through dual tree-type control paths among plural router boxes is provided to bind various router boxes to expand the bound boxes into one single router system and to simplify a control path configuration in accordance with the expansion and a malfunction coping method, thereby increasing availability and reliability of the router system. Power is applied(600), and IDs of boxes are read as an internal processor starts operating(601). It is decided whether to boot to sub boxes or to continue a standby box booting process, depending on whether the IDs of the boxes are IDs of the sub boxes(602,603). If not the IDs of the sub boxes, it is decided whether the IDs are IDs of active boxes(604). If not, an OS(Operating System) suited to standby boxes is booted, and a system state is checked(606). It is decided whether active boxes exist within a system(607). According to the decided results, the active boxes are booted(608) or the standby boxes are initialized while driving applications(609).
