Abstract
A highly-expandable router configuration technology which flexibly meets the need to increase lines as a network grows. A network information sharing unit is provided in a route calculation unit of each router in a clustered router. The network information sharing unit receives an update notification of network information collected by routing protocol units and sends this update information to all other routers in the clustered router as a network information notification packet. The network information sharing units in the receiving router notifies the routing protocol units of the contents of the received updated information. The routing protocol unit updates the network information thereof based on the notified contents, thereby allowing the network information obtained from all routers outside the clustered router to be shared and the clustered router to be recognized externally as a single router.
