Abstract

The embodiment of the present invention discloses a method for obtaining an IPV6 ND address and a BRAS. The BRAS, a broadband remote access server, receives a routing request RS message sent by a user equipment; sends a DHCPV6 Solicit message to a DHCPV6 server configured with a dynamic host setting protocol, and the DHCPV6 The Solicit message carries the DUID of the user equipment and the identity association option IA_PD, so that the DHCPV6 server assigns a 64-bit Delegation prefix to the user equipment according to the IA_PD; sends the 64-bit Delegation prefix to the User equipment, so that the user equipment uses the 64-bit Delegation prefix and the 64-bit IPV6 interface ID to form a 128-bit IPV6ND address. When a network that only supports IPV4 can be upgraded to IPV6 or a dual-stack Dual Stack, the dual-stack It can support IPV4 and IPV6 protocols, and only need to upgrade the DHCP Server to support the distribution of IPV6 prefixes to realize ND access to DHCPV6 access.

Description

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