Abstract

An embodiment of the invention discloses a method for obtaining an IPV6ND address and a broadband remote access server (BARS). The BARS receives a routing request (RS) message sent by a user device. A dynamic host configuration protocol version 6 (DHCPV6) server sends a DHCPV6Solicit message, wherein the DHCPV6Solicit message carries an unique device identifier (DUID) and identity relevance options IA_PD of the user device, so that the DHCPV6 server allocates a 64-bit Delegation prefixion for the user device according to the IA_PD. The 64-bit Delegation prefixion is sent to the user device through a random access (RA) message to enable the user device to use the 64-bit Delegation prefixion and a 64-bit IPV6 interface identity (ID) to form a 128-bit IPV6ND address, and when a network only supporting an IPV4 protocol can be updated and can support an IPV6 protocol or a Dual Stack, the dual stack can support the IPV4 and IPV6 protocols, and ND access and DHCPV6 access can be achieved only by updating the support of a DHCP Server and allocating an IPV6 prefixion.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method for obtaining an IPV6ND address and a BARS. Background technique [0002] Neighbor DiscoVer (Neighbor DiscoVer, ND) and Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol for IPV6, DHCPV6) access are two basic methods for Internet Protocol Version 6 (IPV6) access scenarios. The DHCPV6 access protocol layer supports the use of the remote DHCPV6 server (DHCPV6Server), but the use of ND access can only obtain IPV6ND from the Broadband Remote Access Server (BRAS) because the protocol cannot support the use of the remote DHCPV6 server. address to access the remote DHCPV6 server. [0003] For user equipment that supports DHCPV6 access, the BRAS forwards the received DHCPV6 message to the DHCPV6Server to implement IPV6ND address management, and the BRAS equipment of most manufacturers already supports DHCPV6 access. For user equipment that does n...
