Cisco3640路由器设置

一、 设置路由器管理信息
1、 用扁平控制线接上9孔接头，连接CONSOLE到终端或PC串口，设置终端或直接连至串口的超级终端的参数：BAND率9600，无奇偶校验，8位数据位，1位停止位.
2、 路由器上电，终端屏幕会显示上电过程。
3、 进入特权模式设置口令
line vty 0 4
password bc123
exit
enable secret bc123fzq123
exit
4、 在特权模式设置路由器信息：
hostname bc3640
ip domain-list jzl.cq
ip domain-list jz2.cq
ip domain-name jzl.cq
ip name-sever 10.54.34.1
5、 进入全局模式，配置以太网地址
configure timinal
interface fastethernet 0/0
ip address 192.168.254.254 255.255.255.0
no shutdown
exit
interface fastethernet 1/0
ip address 10.154.34.253 255.255.255.252

二、 CISCO路由器广域网配置向导
1、 dial-on demand routing (ddr)是用公共电话网提供了网络连接。通常的，广域网大多数使用专线连接的，路由器连接到类似MODEM OR ISDNTAS 的数据终端DCE设备上，他们支持同步V.25BITS协议，你可以用SCRIPTS AND DIALER命令设定拨号串。
DDR比较适用于用户对数率要求不高，偶尔有数据传输或只是在特定时候传输数据，比如银行每晚传送报表等等情况下。
当一个感兴趣的包到达路由器时，产生一个DDR请求，路由器发送呼叫建立信息给指定的串口的DCE设备，这个呼叫就把本地的和远程的设备连接起来，一旦没有数据传输，空闲时间开始记时，超过设置的记时时间，连接终止。DDR现在都用静态路由来传输数据，避免路由交换引起的DDR拨号。
和XNS可以通过DDR路由寻址，同步串口，异步串口和ISDN端口可以配置成到一个或多个目的地的DDR连接。
下面是一个典型的DDR连接：
在配置DDR过程中，我们可以把一个或几个物理端口配置成一个逻辑拨号接口，他可以是同步V.25方式，同步DYR启动拨号或异步CHATSCRIPT方式
在端口配置模式下：
在一个端口激活DIAL-ON-DEMAND ROUTING
命令：dialer in-band
指定一个端口为拨号访问组：dialer-group group-number
指定一个单一电话号码：dialer string dialer-string
断线前空前等待时间：dialer idle-time seconds
定义一个或多个目的电话号码表：
dialer map protocol net-hop-address dialer-string
限定传输的access-list表或特定协议：
dialer-list dialer-group list access-list-number或
dialer-list dialer-group protocol protocol name(permit/deny/list access-list-number)
具体配置：
