¿µ¹® ³»¿ë¿ä¾à A DS-Lite B4 device has to know the domain name of the AFTR at the tunnel endpoint to establish an IPv4-over-IPv6 tunnel (i.e., softwire). Thus the AFTR-Name option is newly defined for the delivery of the AFTR information. In the AFTR-Name option, a field is defined so that the domain name of an AFTR can be included in. The DHCPv6 server sets the AFTR-Name option which is sent to the DHCPv6 client (i.e., the B4 device). Then, the DHCPv6 client extracts the domain name of the AFTR specified in the received AFTR-Name option and gets the IPv6 address of the AFTR via the DNS and, finally, established a softwire based on this information.
