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

Embodiment Construction

[0061] The core idea of ​​the present invention is that the relay device generates the first relay message (for example, it can be a DHCPV6 Relay-forward message) according to the network deployment information (for example, it can be VLAN information) of the user equipment, and will carry the network The first relay message of the deployment information is notified to the DHCPV6 server, and the DHCPV6 server assigns an IPV6 routing prefix to the user equipment belonging to the network deployment information according to the network deployment information, and passes the IPV6 routing prefix to the relay device.

[0062] After the relay device obtains the IPV6 routing prefix, it stores it in its own ND routing prefix entry. When the user equipment requests the IPV6 routing prefix or the relay device actively delivers the IPV6 routing prefix, the routing prefix discovery mechanism of the ND protocol will The IPV6 routing prefix is ​​delivered to the user equipment, thereby comple...

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...
