一、实验目的

让如下图所示的拓扑环境实现全网可达

---

二、实验需求

1.R2为ISP，在R2上面只能配置IP地址，R2有一个环回路段

2.R1-R2之间为HDLC封装

3.R2-R3之间为PPP封装，pap认证，R2为主认证方，R3为被认证方

4.R2-R4之间为PPP封装，chap认证，R2为主认证方，R4为被认证方

5.R1、R3、R4之间构建MGRE环境，仅R1的IP地址固定

6.内网使用RIP路由信息协议获取路由，所有PC可以互相访问，并且可访问R2的环回

三、实验步骤

1、各个接口配置IP地址

1)AR1

[R1]int GigabitEthernet 0/0/1

[R1-GigabitEthernet0/0/1]ip address 192.168.1.2 24

[R1-GigabitEthernet0/0/1]int Serial 4/0/0

[R1-Serial4/0/0]ip address 12.1.1.1 24

2)AR2

[R2]int Serial 4/0/0

[R2-Serial4/0/0]ip add 12.1.1.2 24

[R2-Serial4/0/0]int Serial 4/0/1

[R2-Serial4/0/1]ip address 32.1.1.1 24

[R2-Serial4/0/1]int s 3/0/0

[R2-Serial3/0/0]ip address 42.1.1.1 24

[R2]interface LoopBack 0

[R2-LoopBack0]ip address 1.1.1.1 24

3）AR3

[R3]int Serial 4/0/0

4）AR4

[R4]interface Serial 4/0/0

[R4-Serial4/0/0]ip address 42.1.1.2 24

[R4]interface g0/0/1

[R4-GigabitEthernet0/0/1]ip address 192.168.3.1 24

IP分配如下图所示

 

2、HDLC封装

1）AR1

[R1]int Serial  4/0/0

[R1-Serial4/0/0]link-protocol hdlc 

Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]:y

2）AR2

[R2]int Serial 4/0/0

[R2-Serial4/0/0]link-protocol hdlc 

Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]:y

3、PaP认证

1）AR2

[R2]aaa

[R2-aaa]local-user xx privilege level 15 password cipher 123456

Info: Add a new user.

[R2-aaa]local-user xx service-type ppp

[R2-aaa]int s4/0/1

[R2-Serial4/0/1]ppp authentication-mode pap

2）AR3

[R3]int s4/0/0

[R3-Serial4/0/0]ppp pap local-user xx password cipher 123456

4、Chap认证

1）AR2

[R2]aaa 

[R2-aaa]local-user hh privilege level 15 password cipher 123456

Info: Add a new user.

[R2-aaa]local-user hh service-type ppp 

[R2-aaa]q

[R2]int s3/0/0

[R2-Serial3/0/0]ppp authentication-mode chap

2）AR4

[R4]int s4/0/0

[R4-Serial4/0/0]ppp chap password cipher 123456

[R4-Serial4/0/0]ppp chap user hh

5、构建MGRE环境
