:有劳各位，请教CISCO 2611如何进行DDN配置，能否好心给出详细攻略，另外还想麻烦大家就是对一台旧的有口令的2611如何进行恢复（有一块广域网卡），即回到初始设置状态，谢谢各位。

1： ddn可以encap很多。下面配置为ppp(简单配置，仅供参考）
Router1:
hostname router1
username router2 password xxx
interface Serial0
ip address 192.200.10.1 255.255.255.0
clockrate 1000000
ppp authentication chap
!
Router2:
hostname router2
username router1 password xxx
interface Serial0
ip address 192.200.10.2 255.255.255.0
ppp authentication chap
