Embodiment 1

[0036] This embodiment describes the process of configuring IPv6 transition technology configuration parameters for a CPE by using a DHCPv6 protocol message.

[0037] Combine the following figure 2 , detailing the process of configuring IPv6 transition technical parameters for CPE during the process of IPv6 address and network parameter allocation, as shown in the figure, the process includes the following steps:

[0038] In step 201, the CPE broadcasts and sends a DHCPv6-Solicit message (DHCPv6 configuration parameter request message) to request a server in the network to assign an IPv6 address and network configuration parameters to it.

[0039] In step 202, the server sends a DHCPv6-Advertise message (DHCPv6 Advertisement message) to the CPE according to the DHCPv6-Solicit message, to notify the CPE of its allocated IPv6 address and network configuration parameters.

[0040] Specifically, after receiving the DHCPv6-Solicit message sent by the CPE, the server selects an IP...

Embodiment 2

[0063] This embodiment describes the process of specifying the IPv6 transition technology configuration parameters of the CPE through the DHCPv6 stateless configuration.

[0064] A DHCPv6 server can assign other network configuration parameters to clients that already have an IPv6 address. This process is called DHCPv6 stateless configuration, such as image 3 As shown, the process includes the following steps:

[0065] Step 301, when the CPE device is initialized, the CPE sends a DHCPv6-Router-solicit message (DHCPv6 router solicitation message) to the server to request to allocate an IPv6 address to it.

[0066] Step 302, the server sends a DHCPv6-Router-advertise message (DHCPv6 router advertisement message) to the CPE according to the DHCPv6-Router-solicit message.

[0067] When the managed address configuration flag M in the DHCPv6-Router-advertise message is 0, and the other configuration flags O are 1, it means that the server notifies the CPE to obtain an IPv6 address...

Abstract

The invention discloses a method and equipment for configuring the IPv6 transitional technologies on CPE. The method includes the steps that a server receives a DHCP/DHCPv6 request message sent by the CPE; the server caries out processing according to the DHCP/DHCPv6 request message and returns response messages of corresponding protocols to the CPE, an option carrying IPv6 transitional technology configuration parameters is encapsulated in the response messages of the corresponding protocols, and the IPv6 transitional technology configuration parameters are used for indicating the CPE to communicate by means of corresponding IPv6 transitional technologies. The problems generated in the process of configuring the CPE and managing the IPv6 transitional technologies between operators, users and CPE manufacturers are solved, transformation quantity of the server and the CPE is small, and the method is easy to implement; extra message exchange burdens between the CPE and the server are not increased, and bandwidth resources are saved.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method and equipment for configuring IPv6 transition technology on a CPE (Customer Premise Equipment, user end equipment). Background technique [0002] Currently, IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) addresses have been basically exhausted, and a transition to IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) is underway. Generally speaking, IPv6 transition technologies can be divided into three categories: dual stack, tunnel, and translation, and there are dozens of specific technologies. [0003] Telecom operators and equipment manufacturers have different approaches to IPv6 transition technology. Operators may choose a single IPv6 transition technology. In the same network area, such as the same BRAS (Broadband Remote Access Server, Broadband Remote Access Server), only one IPv6 transition technology is used; ...
