一、项目介绍需求分析: (1)总部和分部要求网络拓扑简单,方便维护,网络有扩展和冗余性; (2)总部分财务部,人事部,工程部,技术部,提供有一定的安全性; (3)总部要求核心交换机具有冗余性,可靠性; (4)总部的数据有一定的私密性,不允许外部网络及分公司访问,采用防火墙配置DMZ区域; (5)外部网络有两条运营商线路互为备份,流量主走电信,联通为备用。 二、设计方案及规划1.相关规划说明(包括DHCP、WWW、HTTP等服务相关的参数配置说明) (1)该企业网采用三层架构; (2)终端层8台PC机,两两划分为一个部门,分别为财务部,人事部,工程部,技术部,并划分各自的vlan,分别是vlan10,vlan20,vlan30,vlan40; (3)接入层,使用4台二层交换机,用于用户终端的接入,设计其与终端层各PC机间的端口类型为access类型; (4)汇聚层,使用4台三层交换机,设计其与接入层各交换机间的端口类型为trunk类型。该层采用的技术有:OSPF,VLAN划分,MSTP,VRRP等技术; (5)核心层,使用2个路由器,用于连接让其内网实现互通,采用的技术有:OSPF等技术。 (6)防火墙区,分三个区域DMZ区域(数据中心)、Trust区域(内网)、Untrust区域(外网)。 1.1网络IP地址规划 交换机lsw1,2,3,4,9,10使用交换机S3700,交换机lsw5,6,7,8,11使用交换机S5700,路由器整体使用AR1220与AR2220,防火墙USG600V.
1.2网络管理设计 (1)内部员工都需要访问外网; (2)不同部门之间能够实现相互通信; (3)总部可以访问到外网及分部的部门,但是外网不能访问到内网。 三、设计内容及步骤三个防火墙,3台台服务器,三台S5700交换机,五台S700交换机,六台路由器,十二台PC 基本配置: LSW2如LSW1配置相同 例: LSW1 sys undo info en sys LSW1 vlan batch 10
