Topology information automatic configuration method and its topology information automatic configuration system

摘要

A topology information automatic configuration method for configuring topology information indicating how to connect each equipment, based on configuration information, including IP address and subnet mask, established for every interface of each equipment connected to a network, comprising: a network address calculation step for obtaining network address of a subnetwork to which an interface is connected, as for every interface, based on the IP address and the subnet mask of the interface; and a topology information configuration step for configuring the topology information indicating that each equipment including an interface having the identical network address obtained in said network address calculation step, is connected to the subnetwork of the above identical network address and that the equipment having a plurality of interfaces connect together the subnetworks indicated by the network addresses of the plurality of interfaces obtained in said network address calculation step.
