--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Would you like to enter the initial configuration dialog? [yes]: 回车
First, would you like to see the current interface summary? [yes]: 回车
Any interface listed with OK? value "NO" does not have a valid configu
ration
Interface IP-Address OK? Method Status

Configuring global parameters:
Enter host name [Router]: Router (路由器取名为Router)
The enable secret is a one-way cryptographic secret used
instead of the enable password when it exists.
Enter enable secret: cisco (设置路由器高级口令为cisco)
The enable password is used when there is no enable secret
and when using older software and some boot images.
Enter enable password: user (设置路由器低级口令为user
Enter virtual terminal password: cisco (设置路由器虚终端口令为cisco )
Configure SNMP Network Management? [yes]: 回车
Community string [public]: 回车
Configure IP? [yes]: 回车
Configure IGRP routing? [yes]: no (不采用IGRP协议路由)
Configure RIP routing? [no]: 回车
Configuring interface parameters:
Configuring interface Ethernet0:
Is this interface in use? [yes]: 回车
Configure IP on this interface? [yes]: 回车
IP address for this interface: 86.101.3.20 (输入本路由器局域网口IP地址)
Number of bits in subnet field [0]:16
