no ip domain-lo                    << 禁用 DNS

lin c 0                             

logg s                            << 显示同步

exec-t 0 0                         << 配置超时

exit

 

in s0/0

ip ad 192.168.1.1 255.255.255.0       << 配置 IP 地址掩码

encapsulation ppp                   << 封装协议为 PPP

ppp authentication chap              << 启用 CHAP 认证

ppp chap hostname zsc               << 配置主认证方发出的认证用户名

no sh

exit

in s0/1

ip ad 192.168.1.2 255.255.255.0

encapsulation ppp

ppp authentication chap pap <<ppp 混合认证 , 先采用 CHAP 认证 , 失败后采用 PAP 认证

ppp chap hostname zsc

no sh

exit

username td01 password 0 123        << 配置认证数据库 ( 被认证方的主机名和密码 )

username td02 password 0 456

exit
