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
