PPP协议实验扩展

实验目的:

配置企业中的专线常用协议PPP,理解PPP的工作原理,单向认证与双向认证的使用场合

实验环境拓扑图及要求:

image

 

拓扑图:两台路由器A和B用串口线相连,PC机可用loopback接口模拟。

任务1

要求:

RA和RB之间三条串口线相连,完成PPP捆绑。无认证,无地址协商。实现全网互通。

实验步骤:【必写】

RA的配置:

En

Conf t

hostname RA

int s0/0

ip add 192.168.10.1 255.255.255.0 //配置端口IP

no sh

exit

interface Multilink1 //配置多链路PPP捆绑

ip address 192.168.20.1 255.255.255.0 //配置IP

ppp multilink //配置PPP多链路

ppp multilink group 1

no sh

exit

interface Serial1/1

no sh

encapsulation ppp //配置封装协议

ppp multilink

ppp multilink group 1 //加入PPP多链路1

exit

interface Serial1/2

no sh

encapsulation ppp

ppp multilink

ppp multilink group 1 //加入PPP多链路1

exit

interface Serial1/3

exit

ip route 192.168.30.0 255.255.255.0 192.168.20.2 //配置静态路由

end
