Abstract
A core switching device has a virtual path table and an address table, and selectively performs a PBB operation and a virtual path operation. The virtual path table retains a correspondence relation between a service instance identifier and two ports in a plurality of ports set in advance. The address table retains a correspondence relation between the plurality of ports and an encapsulation address. The core switching device relays an encapsulated frame based on the address table in the PBB operation and relays an encapsulated frame containing the service instance identifier retained in the virtual path table between the two ports retained in the virtual path table in the virtual path operation.
