第三章综合实验

第三章综合实验

一、实验拓扑

  • 二、实验需求

1、R5为ISP,只能进行IP地址配置,其所有地址均配为公有IP地址;

2、R1和R5间使用PPP的PAP认证,R5为主认证方;

R2与R5之间使用pp的CHAP认证,R5为主认证方;

R3与R5之间使用HDLC封装;

3、R1、R2、R3构建一个MGRE环境,R1为中心站点,R1、R4间为点到点的GRE;

4、整个私有网络基本RIP全网可达;

5、所有PC设置私有IP为源IP,可以访问R5环回。

三、实验思路

1、配置IP地址

2、私网通,公网通---配置静态路由协议,测试公网通

3、配置R1-R5的ppp的pap认证,R5为主认证方

4、R2与R5之间使用ppp的CHAP认证,R5为主认证方;

5、R3与R5之间使用HDLC封装;

6、配置GRE VPN

7、配置MGRE VPN

(1)配置NHRP协议,构建公共隧道

(2)配置NHRP 协议使分支机构将自己的隧道地址和公网地址发给总部

(3)配置RIPV2,传递两端的私网路由,实现总部和分部,分部和分部之间的互通

(4)在中心站点上开启伪广播功能

(5)关闭中心和分支站点的RIP的水平分割机制

四、实验步骤

1、配置IP地址,配置静态路由协议,测试公网通

[R1-Serial4/0/0]ip add 15.1.1.1 24

[R2-GigabitEthernet0/0/0]ip add 192.168.2.254 24

[R5]interface LoopBack 0

[R5-LoopBack0]ip address 5.5.5.5 24 // R5回环,作为测试目标

私网公网连通--配静态路由

[R1]ip route-static 0.0.0.0 0 15.1.1.5

[R2]ip route-static 0.0.0.0 0 25.1.1.5

[R3]ip route-static 0.0.0.0 0 35.1.1.5

[R4]ip route-static 0.0.0.0 0 45.1.1.5

查看IP配置:

2、R1和R5间使用ppp的PAP认证,R5为主认证方;

[ISP]aaa

[ISP-aaa]local-user wangdaye password cipher wdy12345 privilege level 15

[ISP-aaa]local-user wangdaye service-type ppp//设置主验证方提供的服务类型

[ISP-Serial4/0/1]ppp authentication-mode pap

[ISP-Serial4/0/1]q

R1被认证方:

[R1-Serial4/0/0]ppp chap user wangdaye//告知被验证方,验证的方式及用户名和密码

[R1-Serial4/0/0]ppp chap password cipher wdy12345

[R1-Serial4/0/0]ppp pap local-user wangdaye password cipher wdy12345

[R1-Serial4/0/0]q

R2与R5之间使用ppp的CHAP认证,R5为主认证方;

[ISP]int s3/0/1

[ISP-Serial3/0/1]ppp authentication-mode chap//R2和R5用ppp的CHAP认证

[ISP-Serial3/0/1]q

R2被认证方:

[R2-Serial4/0/0]ppp chap user wangdaye

[R2-Serial4/0/0]ppp chap password cipher wdy12345

[R2-Serial4/0/0]ppp pap local-user wangdaye password cipher wdy12345

[R2-Serial4/0/0]q

R3与R5之间使用HDLC封装:

[ISP]int s 4/0/0

[ISP-Serial4/0/0]ppp authentication-mode chap

[ISP-Serial4/0/0]link-protocol hdlc//设置接口报文的封装模式

[R3-Serial4/0/0]ppp chap user wangdaye

[R3-Serial4/0/0]ppp chap password cipher wdy12345

[R3-Serial4/0/0]ppp pap local-user wangdaye password cipher wdy12345
