--- 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

Protocol

Ethernet0 unassigned NO unset up

Serial1 unassigned NO unset down

down

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

Class A network is 86.0.0.0, 16 subnet bits; mask is 255.255.255.0

Configuring interface Serial0:

Is this interface in use? [yes]: 回车

Configure IP on this interface? [yes]: 回车

Configure IP unnumbered on this interface? [no]: 回车

IP address for this interface: 86.101.254.3 (输入本路由器广域网口IP地址)

Number of bits in subnet field [0]:16

Class A network is 86.0.0.0, 16 subnet bits; mask is 255.255.255.0

Configuring interface Serial1:

Is this interface in use? [yes]: no (不使用本广域网口)
