Method and device for processing internet protocol version 6(IPV6) routing prefix

Abstract

The invention discloses a method for processing an internet protocol version 6 (IPV6) routing prefix. The method is characterized in that trunk equipment acquires network disposition information of user equipment, and the network disposition information is the classification information of the user equipment; the trunk equipment sends the network disposition information to a dynamic host configuration protocol version (DHCPV6) server; the trunk equipment receives an IPV6 routing prefix from the DHCPV6 server; and the trunk equipment memories the IPV6 routing prefix. In the invention, the IPV6 routing prefix has simple disposition and wider application.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a processing method and device for an IPV6 routing prefix. Background technique [0002] With the rapid development of the Internet, the deficiencies of IPV4 (Internet Protocol version 4, Internet Protocol Version 4) have become increasingly obvious. Aiming at many problems of IPV4, an alternative protocol IPV6 (Internet Protocol Version 6, Internet Protocol Version 6) has been introduced. Compared with IPV4, the IPV6 protocol can provide more functions, for example, provide sufficient address space, hierarchical network structure, support automatic address configuration, etc., many users can obtain enough addresses through the IPV6 network to meet the continuous Increased user demand. [0003] An IPv6 address is divided into two parts, the subnet prefix and the interface identifier. Among them, the subnet prefix is ​​used for route selection, and the interface identifie...

AI Technical Summary

Problems solved by technology

[0015] However, the defect of Scheme 1 is that users must use the DHCPV6 stateful automatic configuration method to automatically obtain an IPV6 address and routing prefix. One has a relatively large use limitation

[0016] The defect of the second scheme is that since the uplink interface of the relay device can only dynamically obtain a DHCPV6 address, the obtained routing prefix is ​​also unique (that is, the network segment corresponding to the IPV6 address), so that the entire relay device can only download Send a routing prefix, that is, the whole machine only supports the division of one VLAN, which cannot realize the complex application of multiple VLANs and multiple users, and there are also great application restrictions

[0017] The defect of solution three is: the relay device must be authenticated by PPPOE, otherwise the relay device cannot carry the user information to the authentication server, and it cannot distinguish between users to issue routing prefixes, that is, the implementation of solution three must be used in conjunction with PPPOE authentication , there is also a large application limitation
