Abstract: PURPOSE: A routing information managing method of a router supporting an RIP protocol is provided to prevent consumption of a network resource according to a routing information broadcast by instantly broadcasting routing information including only a changed entry to the adjacent routers when one entry information is changed and broadcasting only a header of an RIP packet. CONSTITUTION: When a topology is changed in a network, such as cut-off of a link of a disturbance of a router, a router checks whether entry information of its routing table is changed(ST21). If the entry information of the routing table is changed, the router sets a state flag for the changed entry of the routing table as a new state or a corrected state(ST22), and broadcasts the changed entry information together with the entry state information to adjacent routers(ST23). When a RIP packet for the changed entry information is normally broadcast, the state flag for the broadcast entry of the routing table is changed to a still state(ST24). If the entry information of the routing table is not changed, the router checks whether it reaches a period time for periodical routing information broadcasting(ST25). If it reaches a period time, the router broadcasts only a header of the RIP packet to the adjacent routers for the periodical routing information broadcasting in a manner that it sets a command field contained in the header portion of the RIP packet as an effective router packet(ST26).
