PPP Over FR & RIP v2明文认证

R5:

interface Virtual-Template1//C、进入模板就和配置PPP一样了，配置IP，和封装。

ip address 25.0.0.5 255.255.255.0

!

interface Serial0//A、在接口封装FR,并且打开接口（no sh）

no ip address

encapsulation frame-relay

no frame-relay inverse-arp

!

interface Serial0.1 point-to-point//B、创建子接口，再启用一个模板

frame-relay interface-dlci 602 ppp Virtual-Template1

key chain cisco//A、定义一个明文的key,

key 1

key-string cisco

interface Virtual-Template1

ip address 25.0.0.2 255.255.255.0

ip rip authentication key-chain cisco//调用key，完成rip的认证
