Inter technology is playing more and more important role and the construction of hardware, as a basis of inter technology, is gradually.Nowadays, it is mon to use Inter for transferring the information. As requirement of working automatically with information technology, pany needs to build up local area work as to increase working efficiency, expedite information exchange and acmodate modernization of working. Advantages and disadvantages of Enterprise LAN is one of the important standard to judge the petitiveness for enterprise. Especially for training pany which has bination of administration, training and certification. To build up a pany LAN is requested many aspects, which should be proceeded step by step .Firstly, it needs a suitable requirement analysis and design plans. Secondly, it needs to find solution of how to arrange wires, selection and configuration of LAN equipment and server. Finally, it is a need to optimize LAN and set up configuration of security. It needs the steps to deal with .......This thesis how to illustrate and design the Local Area Network for enterprises.This paper from the general on the local area work construction, target, idea, paper analyses the present situation of research at home and abroad, and then the LAN specific needs analysis, integrated wiring design principles, work equipment selection, specific work configuration, etc. From all aspects of the local area work construction planning of the proposed plan, specific application in the OSPF, EIGFP, BGP routing protocols, such as VLAN, ACL, NAT, stub, NSSA and other work optimization technology and AAA authentication, the authentication, Tel HSRP hot backup, passive PASSIVE interface, maintaining security technology mode of VTP, and strive to achieve a plete work training pany LAN. Keywords: LAN, OSPF routing protocols, VLAN area, AAA authentication 中山大學(xué)南方學(xué)院 2022 屆本科生畢業(yè)設(shè)計(jì)III 目 錄第 1 章 緒論 .........................................................1 研究背景及研究意義 ..........................................1 研究現(xiàn)狀 ....................................................2 國外研究現(xiàn)狀 ..............................................2 國內(nèi)研究現(xiàn)狀 ..............................................2 研究的主要內(nèi)容 ..............................................3 本文的組織 ..................................................3第 2 章 相 關(guān) 技 術(shù) 和 概 念 ..........................................4 OSPF 協(xié) 議 （ 開 放 式 最 短 路 徑 優(yōu) 先 協(xié) 議 ） ...................4 VLAN 技 術(shù) （ 虛 擬 局 域 網(wǎng) ） ..................................5 ACL 技 術(shù) （ 訪 問 控 制 列 表 ） .................................6第 3 章 局 域 網(wǎng) 需 求 分 析 ..........................................8 局 域 網(wǎng) 設(shè) 計(jì) 概 述 ............................................8 局 域 網(wǎng) 設(shè) 計(jì) 要 求 ............................................8 網(wǎng)絡(luò)設(shè)計(jì)拓?fù)鋱D ................................................9 局域網(wǎng)設(shè)計(jì)用例描述 ............................................9 用例列表 ..................................................9 用例描述 .................................................10第 4 章 局域網(wǎng)整體設(shè)計(jì) ..............................................13 局域網(wǎng)核心層設(shè)計(jì) .............................................13 局域網(wǎng)匯聚層設(shè)計(jì) .............................................13 局域網(wǎng)接入層設(shè)計(jì) .............................................14 局域網(wǎng) IP 地址劃分及 VLAN 規(guī)劃 .................................15 VLAN 規(guī)劃 ................................................15 IP 地址劃分 ..............................................15 局域網(wǎng)路由協(xié)議選擇 ...........................................16第 5 章 局域網(wǎng)詳細(xì)設(shè)計(jì) ..............................................18 局域網(wǎng)行政模塊詳細(xì)設(shè)計(jì) .......................................18 設(shè)計(jì)概述 .................................................18 配置命令 .................................................18 局域網(wǎng)教學(xué)模塊詳細(xì)設(shè)計(jì) .......................................21中山大學(xué)南方學(xué)院 2022 屆本科生畢業(yè)設(shè)計(jì)III 設(shè)計(jì)概述 .................................................21 配置命令 .................................................21 局域網(wǎng)考試中心詳細(xì)設(shè)計(jì) .......................................23 設(shè)計(jì)概述 .................................................23 配置命令 .................................................23 局域網(wǎng) XX 總部詳細(xì)設(shè)計(jì) ........................................25 設(shè)計(jì)概述 .................................................25
