1企业网系统集成一需求分析1.企业网利用私有专用地址进行内部网络的组织，因为这些地址在实际的生活中对internet是无效的IP，所以不能利用路由协义让其与外部的子网进行路由学习。2.总部有两个VLAN要求在E126交换机上正确的规划和实现，并在R1上对这两个VLAN进行单臂路由。3.企业网VLAN之间能够互相访问。4.以上TOP为一个企业网但是被分隔在三个不同的地理位置，要求总部使用多点的帧中继与分支企业相接，而分支企业使用物理接口的帧中继与总部相接。5.企业网分支2里面有两个子网利用环回地址来模拟实现。6.要求整个企业网启动OSPF的路由。7.确保路由学习的正确性。8.企业网分支1有一个WEB和一个DNS服务器，要求实现WEB和DNS服务（可在Windows2003Server中实现）。总部有一个邮件服务器，要求能实现用户之间的邮件收发。9.在VLAN3的主机上PING：r3.cqust.com要求由202.202.1.2应答。10.您的私有专用网络的主机能访问internet上的WEB（www.cqustlab.com）11.总部和分支1、分支2、总部之间可以进行基于H.323协议的IP电话互通。(未做)2二概要设计2.1拓扑图图2.1整体网络拓扑结构图2.2概述总部有两个VLAN要求在E126交换机上正确的规划和实现，并在R1上对这两个VLAN进行单臂路由。企业网VLAN之间能够互相访问。企业网利用私有专用地址进行内部网络的组织，因为这些地址在实际的生活中对internet是无效的IP，所以您不能利用路由协义让其与外部的子网进行路由学习。以上TOP为一个企业网但是被分隔在三个不同的地理位置，要求总部使用多点的帧中继与分支企业相接，而分支企业使用物理接口的帧中继与总部相接。企业网分支2里面有两个子网利用环回地址来模拟实现。要求整个企业网启动OSPF的路由。确保路由学习的正确性。企业网分支1有一个WEB和一个DNS服务器，要求实现WEB和DNS服务（可在Windows2003Server中实现）。总部有一个邮件服务器，要求能实现用户之间的邮件收发。在VLAN3的主机上PING：r3.cqust.com要求由202.202.1.2应答。您的3私有专用网络的主机能访问internet上的WEB（www.cqustlab.com）三详细设计3.1详细配置清单3.1.1交换机配置3.2R1上的配置如下：version12.2noservicetimestampslogdatetimemsecnoservicetimestampsdebugdatetimemsecnoservicepassword-encryptionhostnameSwitchinterfaceFastEthernet0/1switchportmodetrunkinterfaceFastEthernet0/2switchportaccessvlan2switchportmodeaccessinterfaceFastEthernet0/3switchportaccessvlan3interfaceFastEthernet0/4interfaceFastEthernet0/5interfaceFastEthernet0/6interfaceFastEthernet0/7interfaceFastEthernet0/8interfaceFastEthernet0/9interfaceFastEthernet0/10interfaceFastEthernet0/11interfaceFastEthernet0/12interfaceFastEthernet0/13interfaceFastEthernet0/14interfaceFastEthernet0/15interfaceFastEthernet0/16interfaceFastEthernet0/17interfaceFastEthernet0/18interfaceFastEthernet0/19interfaceFastEthernet0/20interfaceFastEthernet0/214interfaceFastEthernet0/22interfaceFastEthernet0/23interfaceFastEthernet0/24interfaceGigabitEthernet1/1interfaceGigabitEthernet1/2interfaceVlan1noipaddressshutdownlinecon0linevty04loginlinevty515loginend3.1.2R1配置清单version12.4noservicetimestampslogdatetimemsecnoservicetimestampsdebugdatetimemsecnoservicepassword-encryptionhostnameR1ipsshversion1interfaceFastEthernet0/0noipaddressduplexautospeedautointerfaceFastEthernet0/0.1encapsulationdot1Q2ipaddress192.168.2.1255.255.255.0interfaceFastEthernet0/0.2encapsulationdot1Q3ipaddress192.168.3.1255.255.255.0interfaceFastEthernet0/1noipaddressduplexautospeedautoshutdowninterfaceSerial0/0/0ipaddress202.202.1.1255.255.255.0encapsulationframe-relayframe-relaymapip202.202.1.2103interfaceSerial0/0/1noipaddress5shutdowninterfaceModem0/1/0noipaddressinterfaceModem0/1/1noipaddressinterfaceVlan1noipaddressshutdownrouterospf1log-adjacency-changesnetwork192.168.2.00.0.0.255area0network192.168.3.00.0.0.255area0network202.202.1.00.0.0.255area0network202.202.2.00.0.0.255area0routerripipclasslessnocdprunlinecon0linevty04loginend3.1.3R2配置清单version12.4noservicetimestampslogdatetimemsecnoservicetimestampsdebugdatetimemsecnoservicepassword-encryptionhostnameR2ipsshversion1interfaceFastEthernet0/0ipaddress88.88.88.1255.255.255.0duplexautospeedautointerfaceFastEthernet0/0.1encapsulationdot1Q2noipaddressinterfaceFastEthernet0/1noipaddressduplexautospeedautoshutdowninterfaceModem0/0/0noipaddress6interfaceModem0/0/1noipaddressinterfaceSerial0/1/0ipaddress202.202.2.2255.255.255.0encapsulationframe-relayframe-relaymapip202.202.1.1201broadcastframe-relaymapip202.202.1.2203broadcastinterfaceSerial0/1/1noipaddressshutdowninterfaceVlan1noipaddressshutdownipclasslessiproute192.168.2.0255.255.255.0202.202.1.1iproute88.88.88.0255.255.255.0202.202.1.2iproute88.88.88.0255.255.255.0202.202.1.1linecon0linevty04loginend3.1.4R3配置清单version12.4noservicetimestampslogdatetimemsecnoservicetimestampsdebugdatetimemsecnoservicepassword-encryptionhostnameR3ipsshversion1interfaceLoopback0ipaddress202.202.100.1255.255.255.0interfaceLoopback1ipaddress202.202.101.1255.255.255.0interfaceFastEthernet0/0noipaddressduplexautospeedautoshutdowninterfaceFastEthernet0/1noipaddressduplexautospeedautoshutdown7interfaceModem0/0/0noipaddressinterfaceModem0/0/1noipaddressinterfaceSerial0/1/0ipaddress202.202.1.2255.255.255.0encapsulationframe-relayframe-relaymapip202.202.1.1301broadcastframe-relaymapip202.202.2.2302broadcastinterfaceSerial0/1/1noipaddressshutdowninterfaceVlan1noipaddressshutdownrouterospf1log-adjacency-changesnetwork202.202.1.00.0.0.255area0network202.202.2.00.0.0.255area0ipclasslesslinecon0linevty04loginend3.2帧中继FR配置图3.2.1帧中继FR配置
