NETWORK-CONFIGURATION-INFORMATION GENERATION METHOD AND COMMUNICATION DEVICE

A network-configuration-information generation method generates information indicating a network configuration of a network system defined by a plurality of communication devices and a plurality of networks. The method includes: a step in which at least one of the communication devices generates and stores network-configuration information defined as a pair of a network name of a network to which the at least one communication device belongs and a network name of a network adjacent to the network to which the at least one communication device belongs; and steps in which when each communication device receives, from another communication device, the network-configuration information stored in the other communication device, each communication device stores the received network-configuration information.
