路由器使用PPP协议互联

 

 AR1配置

local-user huawei password cipher %$%$6t='8KiYDPz28R<zS4U3}rhP%$%$
 local-user huawei service-type ppp
在AR1上配置地址，CHAP认证和给对端分配地址。
interface Serial4/0/0
 link-protocol ppp
 ppp authentication-mode chap 
 remote address 12.1.1.2 
 ip address 12.1.1.1 255.255.255.0 

AR2配置

在AR2上配置CHAT认证及用自动方式获取IP地址。
interface Serial4/0/0
 link-protocol ppp
 ppp chap user huawei
 ppp chap password cipher %$%$n9BmS2i/|)B!n9&fnVCK,";3%$%$
 ip address ppp-negotiate
