In a virtual LAN, a packet forwarding apparatus forwards IP packets and L2 packets using a single switch. The packet forwarding apparatus includes a switch that switches a media access control (MAC) packet using a MAC address of the MAC packet, and a packet format converter. The packet format converter converts a packet from an input and output unit into a packet having a MAC address according to information from the input and output unit, and converts a packet output from the switch to the input and output unit to a packet format compatible with the input and output unit according to the information of the input and output unit.
