二、实验场景:
H公司的网络拓扑图如上,网络环境描述如下:
- RTB是H 公司汇聚层路由,并且是连接外部网络的出口路由器
- SWA 连接公司局域网用户PCA,PCA通过在RTB 上配置的NAT转换访问公网
- 公司用户PCB要求可以远程登录内网路由器RTA
- SWB和RTA之间通过以太网连接,使用RIPV2实现互联
- RTA和RTB之间通过PPP以及RIPV2实现互联,RTA和RTB之间配置CHAP 双向认证
- SWA和SWB ,RTB和SWC 之间使用以太网,配置静态路由实现互联
三、实验要求:
请搭建并配置H公司网络,要求:
- 根据图示完成拓扑链接,并按图示完成标识。
- 正确配置IP 地址,注意接口地址依据所选择设备进行适当调整,例如:G0/1调整为G1/0/1,请在不修改图示IP地址的前提下将其配置在正确的接口上。
- 正确配置SWA和SWB互联接口“G0/23”和“G0/24”间的链路聚合,在保证设备间无环路情况下,成倍提高互联宽带。
- 正确配置RTA和RTB之间的PPP及其CHAP协议双向认证(即RTA和RTB互为认证),两个路由器上的用户名都为CHAP,密码都为test,使得RTA和RTB广域网实现互通。
- 正确配置SWB,RTA,RTB之间的 RIPV2 协议,要求:
- SWA和SWB、RTB和 SWC的互联网段不能使用RIP协议发布路由
- 在配置RIPV2时不允许使用import命令
- PCA可以ping通RTB的 GE0/1接口IP
6.在RTB上配置NAT以及各路由器的静态路由实现H公司局域网用户通过NAT 转换访问SWC及PCB:
- 正确配置访问控制列表,实现只允许PCA所在的网段通过Nat转换访问SWC
- 在RTB上使用NAPT的方式实现NAT转换,NAT地址池为100.1.1.100-100.1.1.110
- 正确配置NAT sever服务,让PCB可以远程Telnet到RTA上配置设备
- 配置合理的静态路由,使得PCA可以ping通PCB
7.在网络中合理的设备上配置ACL,要求:
- PCA和RTA无法相互ping通,但是PCA依然可以ping通网络中其他设备的任一正常工作的接口地址
- PCA无法Telnet到RTA,但PCB可以Telnet到RTA,且以用户名及密码(用户名为user密码:3011)方式登录,登录后具有管理员权限。
