● 试题二

PPP(Point-to-Point Protocol)是SLIP(Serial Line IP protocol)的继承者,它提供了跨过同步和异步电路实现路由器到路由器(router-to-router)和主机到网络(host-to-network)的连接。

CHAP(Challenge Handshake Authentication Protocol,挑战-握手验证协议)和PAP(Pass-word Authentication Protocol,口令验证协议)通常被用于在PPP封装的串行线路上提供安全性认证。使用CHAP和PAP认证,每个路由器通过名字来识别,可以防止未经授权的访问。

路由器Router1和Router2的S0口均封装PPP协议,采用CHAP做认证,如图1所示。

设置如下:

Router1:

hostname router1

username router1 password xxx

interface Serial0

ip address 192.200.10.1 255.255.255.0

encapsulation ppp

clockrate 1000000

ppp authentication chap

!

Router2:

hostname router2

username router2 password xxx

interface Seria10

ip address 192.200.10.2 255.255.255.0

encapsulation ppp

ppp authentication chap

[问题1]上述配置中是否有问题?请指出并说明理由。

[问题2]解释配置中画线部分内容含义?
