| ## 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. |-----------------|-----------------| | Vlan区域 | IP网段 | | Lsw1,PC1,PC2 | 192.168.10.0/24 | | Lsw2,PC3,PC4 | 192.168.20.0/24 | | Lsw3.PC5,PC6 | 192.168.30.0/24 | | Lsw4,PC7,PC8 | 192.168.40.0/24 | | AR7与FW4 | 192.168.97.0/24 | | AR7与AR6 | 192.168.93.0/24 | | AR7,PC11 | 192.168.13.0/24 | | AR7与AR5间 |

（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 1.1设计topo图及连接设备 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

2. vrrp主备切换
DHCP动态地址分配 
1. 防火墙主备切换
2. 
3. NAT源地址转换，当各部门访问外网时都是通过转换后IP地址出去，通过抓包看是否转换成功。
4. NAT目的地址转换，通过http测试。
