扁平化校园网的Ipv6升级建设

The flattening of campus network construction on Ipv6 upgrade

绝大部分高校目前的网络架构都是传统的三层架构模式,而无锡职业技术学院已经逐步实现了校园网的扁平化部署,该模式采用QINQ技术减少了网络的逻辑结构层次,使网络变得更为清晰,利于管理。本文介绍了结合校园网扁平化改造将IPv4网升级到Ipv6网络的建设方案,同时对网络升级改造中遇到的问题进行分析、解决,给出了核心设备的关键配置、升级后的核心拓扑以及最后的路由实现。

Most of the current network architecture is the traditional three layer architecture,Wuxi Institu-te of Technology has gradually realized the flat deployment of campus network.This model uses QINQ technology to reduce the logic structure of network.The network becomes clearer,conducive to the man-agement.The paper introduces the combination of campus net flattening transformation of the IPv4 net-work upgrade to Ipv6 network construction program,and analyzes the problem of network upgrade,solves the core topology configuration,upgrading,and the way to the core equipment and the final routing.
