实验需求

  1. 按照图示搭配拓扑,并配置IP地址

  2. RTA和RTB使用PPP链路直连

  3. 在PCA或PCB上通过ping命令检查PCB或PCA的互通性

实验解析

1、按照图示搭配拓扑,并配置IP地址

步骤1:配置PCA的IP地址以及网关

PPP-PCA

步骤2:配置RTA的IP地址

[RTA]interface g0/0
[RTA-GigabitEthernet0/0]ip address 192.168.1.1 30
[RTA]interface Serial 1/0
[RTA-Serial1/0]ip address 10.1.1.2 30

步骤3:配置RTB的IP地址

[RTB]interface g0/0
[RTB-GigabitEthernet0/0]ip address  192.168.2.1 30
[RTB]interface Serial 1/0
[RTB-Serial1/0]link-protocol ppp
[RTB-Serial1/0]ip address 10.1.1.1 255.255.255.252

步骤4:配置PCB的IP地址以及网关

PPP-PCB

2、RTA和RTB使用PPP链路直连

步骤1:将RTA串行接口封装PPP协议,并修改带宽为2048000

[RTA]interface Serial 1/0
[RTA-Serial1/0]link-protocol ppp
[RTA-Serial1/0]bandwidth 2048000

步骤2:将RTB串行接口封装PPP协议,并修改带宽为2048000

[RTB]interface Serial 1/0
[RTB-Serial1/0]link-protocol ppp
[RTB-Serial1/0]bandwidth 2048000

3、在RTA上配置到达192.168.2.0/30网段的路由

[RTA]ip route-static 192.168.2.0 255.255.255.252 10.1.1.1

4、在RTB上配置到达192.168.1.0/30网段的路由

[RTB]ip route-static 192.168.1.0 255.255.255.252 10.1.1.2

5、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

步骤2:在PCB上ping PCA的IP地址
