A transfer system for bundle transfer, in which the amount of route information and the number of times advertisement is performed are reduced, and maintenance and management are made to be highly efficient to implement improved transfer quality. A path setting section specifies a path between nodes for a receiving side as a bundled link which can have a plurality of paths tied up. A transmission-side route-information advertisement section advertises route information in a network when recognizing that the path has been established. A path recognition section recognizes the path and sets the path as a bundled link. A receiving-side route-information advertisement section advertises the route information in the network when recognizing that the path has been established.
