Abstract:
An edge Bridge (2A) executes Ethernet encapsulation. Even when redundant MAC addresses are used in the network of a customer, the MAC address of the customer is not referred to in a backbone network (1). Since forwarding is done on the basis of a MAC address added by the edge Bridge (2A), correct forwarding is possible. Additionally, in the edge Bridge (2A), a Service VLAN ID based on the customer-facing port which has received a customer MAC frame and the VLAN ID in the customer MAC frame is added to the customer MAC frame, thereby building a completely closed network for each customer. The customer can belong to a plurality of Service VLANs through a single customer-facing port and select, by a VLAN ID, a Service VLAN to which he/she should belong.
