思科路由器配置命令详解及实例
思科路由器配置与命令使用说明
在用户模式下敲“enable”可以进入特权模式conf t 进入全局配置模式hostname lab_a 给路由器命名lab_a(config)#inter e0 //进入e0端口配置模式lab_a(config-if)#ip addr 192.5.5.1 255.255.255.0 //设置e0端口的ip lab_a(config-if)#no shut //激活端口lab_a(config-if)#no shut //激活e1端口lab_a(config-if)#ip addr 201.100.11.1 255.255.255.0 //设置e1端口的iplab_a(config)#inter e1 //进入e1端口配置模式lab_a(config-if)#no shut //激活e1端口lab_a(config-if)#ip addr 205.7.5.1 255.255.255.0 //设置e1端口的ip lab_a(config)#inter s1 //进入s1端口配置模式 lab_a(config-if)#ip addr 201.100.11.1 255.255.255.0 这个为设置s1端口的iplab_a(config-if)#clock rate 56000 //时钟频率为56kb/slab_a(config-if)#exitlab_a(config)#router rip //进入rip协议配置子模式lab_a(config-router)#network 192.5.5.0 //声明网络lab_a(config-router)#network 205.7.5.0lab_a(config-router)#network 201.100.11.0lab_a(config-router)#exit都设置好后就进行测试测试主要用到show和ping 这两个命令 router#show run //显示当前配置你那是普通用户模式当然不对router#show e0 //显示e0口配置router#ping 其他路由器的ip地址或自己端口的ip如果能ping通别的路由器说明你的rip配置成功了1. router>路由器处于用户命令状态，这时用户可以看路由器的连接状态，访问其它网络和主机，但不能看到和更改路由器的设置内容。

但路由器的第一次设置必须通过第一种方式进行,此时终端的硬件设置如下:波特率：9600数据位：8停止位：1奇偶校验: 无二、命令状态1. router>路由器处于用户命令状态，这时用户可以看路由器的连接状态，访问其它网络和主机，但不能看到和更改路由器的设置内容。
2. router#在router>提示符下键入enable,路由器进入特权命令状态router#，这时不但可以执行所有的用户命令，还可以看到和更改路由器的设置内容。

思科路由器配置命令详解及实例
一、路由器基本配置
1.1 登录路由器
为了配置和管理思科路由器，您需要登录到路由器的控制台或通过远程登录方式。
使用以下命令登录路由器，并进行必要的身份验证：
```
Router> enable
Routerconfigure terminal
Enter configuration commands, one per line： End with TL/Z：
Router(config)hostname [路由器名称]
Router(config)enable secret [密码]
Router(config)line console 0
Router(config-line)password [密码]
Router(config-line)logging synchronous
Router(config-line)exit
Router(config)line vty 0 4
Router(config-line)password [密码]
Router(config-line)logging synchronous
```
1.2 配置接口
接下来，您需要配置路由器的接口，以便与其他网络设备进行通信。
使用以下命令配置接口：
```
Router(config)interface [接口类型] [接口编号]
Router(config-if)ip address [IP地址] [子网掩码]
Router(config-if)no shutdown
Router(config-if)exit
```
二、路由配置
2.1 静态路由
静态路由是手动配置的路由项，将特定的网络目的地与下一跳路由器关联起来。
以下是配置静态路由的示例命令：
```
Router(config)ip route [目的网络] [子网掩码] [下一跳地址]
```
2.2 动态路由
动态路由是通过路由协议动态学习并自动更新的路由项。
以下是配置动态路由的示例命令：
```
Router(config)router [路由协议]
Router(config-router)network [本地网络地址]
```
三、NAT配置
网络地址转换（NAT）是一种将私有IP地址转换为公有IP地址的技术，用于在私有网络和公网之间进行通信。
以下是配置NAT的示例命令：
```
Router(config)interface [出口接口]
Router(config-if)ip nat outside
Router(config)interface [内部接口]
Router(config-if)ip nat inside
Router(config)ip nat inside source list [ACL编号] interface [出口接口] overload
```
四、ACL配置
访问控制列表（ACL）用于过滤和限制网络流量。
以下是配置ACL的示例命令：
```
Router(config)access-list [ACL编号] [permit ---- deny] [源地址] [源地址掩码] [目的地址] [目的地址掩码]
Router(config)interface [接口类型] [接口编号]
Router(config-if)ip access-group [ACL编号] [in ---- out]
```

法律名词及注释：
1：静态路由：通过手动配置的路由项来指定网络数据包的下
一跳路径。
2：动态路由：通过路由协议自动学习并更新的路由项来确定
网络数据包的下一跳路径。
3： NAT：网络地址转换，是一种技术，用于在私有网络和公网
之间进行通信，将私有IP地址转换为公有IP地址。
4： ACL：访问控制列表，用于过滤和限制网络流量的规则集合。
