Abstract
An active router and standby routers share routing information used for dynamic routing while in normal operation. Further, the active router and the standby routers share routing information obtained after route computation is performed according to a routing protocol. Thus, efficient operation can be achieved. Protocol engines (31a to 31d) communicate with routers (41 and 42) to compute a route to be selected for routing with respect to a corresponding protocol. When the routing information has changed, a shared routing information transmitter (33) transmits the routing information and the like to the standby routers. Each of the protocol engines in a router operating as an active router communicates with the routers (41 and 42) to compute a route to be selected for routing with respect to a corresponding protocol. When the routing information has changed, a shared routing information receiver (34) receives the routing information and the like transmitted from the protocol engine.
