大型企业网络案例
有线网络结构设计背景
1.1总介绍
中国平安网络，由一个总公司网络、一个分公司网络和一个对外服务区组成。
其中总公司网络和分公司网络在不同的地区，总公司和分公司都有公司内部的访问的数据中心（DMZ区）；对外服务区被托管在中国电信。
路由器ISP模拟运营商中国电信。
2.1总公司
1）Router1作为边界路由也是核心层路由器；sw1、sw2是核心层交换机；sw3、sw4是汇聚层交换机，其中SW3分别连接了总公司部门1，总公司部门2和总公司部门3；SW4分别连接了总公司部门4，总公司部门5，总公司部门6，总公司Server以及无线路由器1。
2）总公司Server只能为公司内部提供服务，不对外提供服务。
部门1,2,3,6均可访问内网Web，Ftp和DNS服务器，部门4只可以访问内网FTP其他的都不可以访问，部门5可以访问内网Web
3.1分公司
Router9是出口路由器，其中sw5、sw4是核心交换机，实现冗余架构；sw6、sw7是汇聚层交换机;其中SW6下面连接了部门1和部门2；SW7连接了部门3，部门4，Server2以及无线路由器2。
内网ACL配置：
部门1，2，4可以访问内网中的Web和Ftp服务器，部门3只可以访问内网的ftp服务器。
4.1中国电信
企业总公司网络的出口路由器router1和分公司网络的出口路由器都与ISP相连接，其中router1和ISP之间使用了ppp广域网协议，启用了chap的认真方式实现与互联网相连；R9使用帧中继技术与ISP相连。
该企业的对外访问服务器托管到中国电信运营商。
二、拓扑结构
总体拓扑：
总公司拓扑：
分公司拓扑：
ISP外网即帧中继：
三、知识点
1.静态路由2.RIP3.单区域OSPF4.EIGRP5.EIGRP非等价负载均衡6.ppp封装（chap）7.帧中继8.ACL访问控制9.NAT地址转换10.STP的配置11.VLAN间的路由12EIGRP手动汇总13.路由重分布14.默认路由15.Telnet16.双链路冗余的备份17.DHCP的使用
四、主要功能
部门1,2,3,6均可访问内网Web，Ftp和DNS服务器。
部门4只可以访问内网FTP其他的都不可以访问。
部门5可以访问内网Web和Ftp但不可以访问DNS。
部门1，2,4可以访问外网Web以及公司总部的Web，Ftp服务器。
部门3只可以访问公司总部的Ftp服务器。
5、主要配置清单
