pap 单向认证问题

请哪位大侠帮忙看看下面的配置为什么还是不能通信:
R1 配置:

Router>en
Router#conf t
Enter configuration commands, one per line.End with CNTL/Z.
Router(config)#hostname R1
R1(config)#user R2 pass aaa
R1(config)#int s 0/0/0
R1(config-if)#ip add 192.168.1.1 255.255.255.0
R1(config-if)#no shut
%LINK-5-CHANGED: Interface Serial0/0/0, changed state to down
R1(config-if)#en ppp
R1(config-if)#ppp auth pap
R1(config-if)#exit

R2配置:
interface Serial0/0/0
ip address 192.168.1.2 255.255.255.0
encapsulation ppp
ppp authentication pap
ppp pap sent-username R2 password 0 aaa
clock rate 64000

ppp authentication pap
表示启用PAP认证你在R2上也开启了 这就变成双向了

把R1的封装取消了还是ping不通,这是啥情况啊?

R2
interface Serial0/0/0
ip address 192.168.10.2 255.255.255.0
encapsulation ppp

你只要把R2上的PAP认证去掉就好了
