Abstract
A frame forwarding apparatus is provided with a frame forwarding processing unit for converting a VLAN ID of a frame received from one subscriber terminal into a group VLAN ID and converting a group VLAN ID of a frame received from an ISP router into a subscriber VLAN ID, by referring to a VLAN bundling table. Each of the entries in the bundling table defines subscriber side line information including a line number of a physical line connected to one of the subscriber terminals and a subscriber VLAN ID, in association with a MAC address of the subscriber terminal and ISP router side line information including a line number of a physical line connected to the ISP router and a group VLAN ID.
