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.
A network information sharing method using routers connecting networks to which communication terminals are connected, said network information sharing method comprising the steps of:
A network information sharing method using routers which have a plurality of route calculation units, one of said plurality of route calculation units being in active state with the rest in backup state, said network information sharing method comprising the steps of:
A network information sharing method using a router in which a plurality of routing protocol programs operate, each of said plurality of routing protocol programs executing a different routing protocol, said network information sharing method comprising the steps of:
A network information sharing method using a plurality of routers connecting networks to which communication terminals are connected, said network information sharing method comprising the steps of:
A router connecting networks to which communication terminals are connected and which allows network information 16 to be shared, said router comprising:
A clustered router comprising a plurality of routers connecting networks to which communication terminals are connected, each of said plurality of routers comprising:
A router which has a plurality of route calculation units and which allows network information to be shared, one of said plurality of route calculation units being in active state with the rest in backup state, said router comprising:
A router in which a plurality of routing protocol programs operate and which allows network information to be shared, each of said plurality of routing protocol programs executing a different routing protocol, said router comprising:
