CCNA实验4:HDLC和PPP

一.HDLC封装

router9和11上分别配置s0/0如下

conf t

int s0/0

encapsulation hdlc

do show int s0/0

ip address x.x.x.1 255.255.255.0

no shutdown





即可互相ping通

二.PPP封装

2.1无认证

conf t

int s0/0

encapsution ppp

no sh

即可.PAP或者CHAP认证是可选的.

2.2单向认证pap

客户端:

ppp pap sent-username r1 password 0 mypass

服务器端:

conf t

username r1 password 0 mypass

int s0/0

encapsution ppp

ppp authentication pap

2.3双向认证pap

客户端:

conf t

username bill password 0 good

int s0/0

encapsution ppp

ppp pap sent-username r1 password 0 mypass

ppp authentication pap

服务器端:

conf t

username r1 password 0 mypass

int s0/0

encapsution ppp

ppp authentication pap

ppp pap sent-username bill password 0 good

2.4 CHAP双向认证

R1:

conf t

username r1 password 0 good

int s0/0

encapsution ppp

ppp authentication chap

R2:

conf t

username r2 passord 0 good

encapsution ppp

ppp authentication chap

2.5 CHAP单向认证—cisco paket tracer中做不了此实验,未验证

r1(config)#username r2 password cisco r1(config)#int s1/1 r1(config-if)#encapsulation ppp r1(config-if)#ppp authentication chap r2(config)#int s1/0 r2(config-if)# encapsulation ppp r2(config-if)#ppp chap hostname r2 // 设置本端用户名 r2(config-if)#ppp chap password cisco
