PPP CHAP认证密码要求

Question

在PPP接口上CHAP认证的要求是什么？我认为两个路由器都必须定义相同的密码，如下所示。

r1> username r2 password demo
r2> username r1 password demo

但是，在数据包跟踪程序示例中指定了以下配置。

!!!! Script for R1 !!!!
username ISP password cisco123
interface s0/0/0
encapsulation ppp
ppp authentication chap
interface tunnel0
tunnel mode gre ip
ip address 192.168.2.1 255.255.255.0
tunnel source s0/0/0
tunnel destination 198.133.219.86


!!!! Script for R2 !!!!
en
conf t
username ISP password 123cisco
interface s0/0/0
encapsulation ppp
ppp authentication chap
interface tunnel0
tunnel mode gre ip
ip address 192.168.2.2 255.255.255.0
tunnel source s0/0/0
tunnel destination 209.165.201.1

每个路由器可以指定自己的密码吗？

r1> username r2 password demo2
r2> username r1 password demo1

Answer 1

路由器1发送的用户名和密码不一定与从路由器2收到的用户名和密码相同。@RickyBeam，谢谢您的反馈。
