实验解析

1、按照图示搭建拓扑,并且配置IP地址

步骤1:在PCA上配置IP地址

PPP CHAP+PPP MP-PCA

步骤2:在RTA上配置IP地址

[RTA]interface GigabitEthernet 0/0
[RTA-GigabitEthernet0/0]ip address 192.168.1.1 30
[RTA]interface Serial 1/0
[RTA-Serial1/0]ip address 10.1.1.1 30

步骤3:在PCB上配置IP地址

[RTB]interface GigabitEthernet 0/0
[RTB-GigabitEthernet0/0]ip address 192.168.2.1 30
[RTB]interface Serial 1/0
[RTB-Serial1/0]ip address 10.1.1.2 30

步骤4:在PCB上配置IP地址

PPP CHAP+PPP MP-PCB

2、在RTA上配置到达192.168.2.0/30网段的路由

[RTA]ip route-static 192.168.2.2 30 10.1.1.2

3、在RTB上配置到达192.168.1.0/30网段的路由

[RTB]ip route-static 192.168.1.1 30 10.1.1.1

4、在RTA配置本地用户以CHAP方式验证对端RTB

步骤1:在RTA上创建本地用户和密码

[RTA]local-user RTB class network 
[RTA-luser-network-RTB]service-type ppp
[RTA-luser-network-RTB]password simple pwdpwd

步骤2:配置RTA的串行接口的配置验证方式为CHAP且为验证方,向对方发送用户名 RTA

[RTA]interface Serial 1/0
[RTA-Serial1/0]ppp authentication-mode chap
[RTA-Serial1/0]ppp chap password simple pwdpwd
[RTA-Serial1/0]ppp chap user RTA  

[RTA]interface Serial 2/0
[RTA-Serial2/0] ppp authentication-mode chap 
[RTA-Serial1/0]ppp chap password simple pwdpwd
[RTA-Serial1/0]ppp chap user RTA

5、在RTB配置本地用户以CHAP方式验证对端RTA

步骤1:在RTB上创建本地用户和密码

[RTB]local-user RTA class network 
[RTB-luser-network-RTA]service-type ppp
[RTB-luser-network-RTA]password simple pwdpwd

步骤2:配置RTB的串行接口的配置验证方式为CHAP且为验证方,向对方发送用户名 RTB

[RTB]interface Serial 1/0
[RTB-Serial1/0]ppp authentication-mode chap
[RTB-Serial1/0]ppp chap password simple pwdpwd
[RTB-Serial1/0]ppp chap user RTB

[RTB]interface Serial 2/0
[RTB-Serial2/0] ppp authentication-mode chap 
[RTB-Serial1/0]ppp chap password simple pwdpwd
[RTB-Serial1/0]ppp chap user RTB

6、分别在RTA和RTB上创建MP-group组

在开始PPP MP实验前,需要将路由器配置恢复到默认状态

步骤1:在RTA上创建MP-group组,并且配置IP地址

[RTA]interface MP-group 1
[RTA-MP-group1]ip address 10.1.1.1 30

步骤2:在RTB上创建MP-group组

[RTB]interface MP-group 1
[RTB-MP-group1]ip address 10.1.1.2 30

7、分别把RTA和RTB的串行接口加入到MP-group组中

步骤1:把RTA的串行接口加入到MP-group组中

[RTA]int range s1/0 s2/0
[RTA-if-range]ppp mp MP-group 1

步骤2:把RTB的串行接口加入到MP-group组中

[RTB]int range s1/0 s2/0
[RTB-if-range]ppp mp MP-group 1

8、在PCA或PCB上通过ping命令检查PCB或PCA的互通性

步骤1:在PCA上ping PCB的IP地址

<H3C>ping 192.168.2.1
Ping 192.168.2.1 (192.168.2.1): 56 data bytes, press CTRL_C to break

步骤2:在PCB上ping PCA的IP地址

<H3C>ping 192.168.1.1
Ping 192.168.1.1 (192.168.1.1): 56 data bytes, press CTRL_C to break
