摘要
L2 switch 1 accommodates a plurality of subscriber lines and is connected to an upper side of an internet including service/management device 5 to exchange data packet. L2 switch 1 transmits broadcast packet of DHCP and ARP among the exchanged data packets to not the side of subscriber line but the upper side of the internet. When L2 packet transfer device 2 transfers the broadcast packet of ARP request to IP address managing device 3, L2 packet transfer device 2 determines whether the ARP request is transmitted from a user terminal connected to the subscriber line or from service/management device 5 or packet transfer device 4. 展开▼
