连接计算机和路由器,以及路由器和*接口,应注意级联线和直通线的用法。
首先确定f0/0与f0/1哪个是*接口 哪个是内网接口
基本路由器配置命令
1.配置f0/0和f0/1的ip地址
Router>en 进入
Password: 输入密码 输入后看不见
Router#config t 进入特权配置模式
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface f0/0 进入f0/0接口
Router(config-if)#no shut 激活f0/0接口
Router(config-if)#ip address 172.16.0.246 255.255.255.0 配置IP地址
Router(config-if)#exit 退出
Router(config)#interface f0/1 进入f0/1接口
Router(config-if)#ip address 192.168.0.1 255.255.255.0 配置IP地址
Router(config-if)#no shut 激活f0/1接口
Router(config-if)#exit 退出
Router(config)#exit 退出
Router#

Router#show run 查看运行状态

2,配置路由和配置NAT内外接口(此包含了NAT转换的一些内容)
Router# 输入的en和密码就省去了 ~_~
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ip route 0.0.0.0 0.0.0.0 172.16.0.254 配置路由信息 (此是一条缺省路由)
Router(config)#interface f0/0 进入F0/0接口
Router(config-if)#ip nat inside 把F0/0设置为接入口(inside)
Router(config-if)#exit
Router(config)#interface f0/1 进入F0/1接口
Router(config-if)#ip nat outside 把F0/1设置为接出口
Router(config-if)#exit
Router(config)#exit
Router#sho -----------------你一定?呵呵这里你只要输入show run 不用管他 只要不输错 就会成功

3,配置NAT 转换的重要一句静态路由:
ip route-static <ip><mask>{interface number|nexthop}[value][reject|blackhole]
Router# 输入的en和密码就省去了 ~_~
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ip nat inside source static 192.168.1.2 172.16.0.246 配置NAT地址的转换信息
Router(config)#exit
Router#show run 查看

shutdown

!
ip nat inside source static 192.168.1.2 172.16.0.246 ------------>配好了
ip classless
ip route 0.0.0.0 0.0.0.0 172.16.0.254
ip http server
ip pim bidir-enable
!
logging facility local3
logging 172.18.1.3

end

有钱人,思科都买了 看不懂下面的就找专业网络公司人员花钱几百大洋调吧,那个路由要用命令的,
既然是学习线面的你应该能看懂自己摸索吧
单臂路由
二层交换机
添加三个vlan
enable
config t
vlan 1
name vlan1
vlan 2
name vlan2
vlan 3
name vlan3
根据需要划分交换机端口到自己的VLAN
把交换机连接路由的口设置为trunk
比如f0/1口
intface fast0/1
switch port mode trunk
switch trunk encapsulation dot1q 封装dot1q
路由设置
路由链接交换机的口不要配置协议
进入子接口
比如路由的口也是f0/1
int f0/1
no ip add
interface fast0/1.1
ip address 192.168.1.1 255.255.255.0
encapsulation dot1q 1
no sh
interface fast0/1.2
ip address 192.168.0.1 255.255.255.0
encapsulation dot1q 2
no sh
interface fast0/1.3
ip address 192.168.1.1 255.255.255.0
encapsulation dot1q 3
no sh
然后启用默认路由到公网
启用nat做地址转换 结合二楼的nat配置 和控制访问列表
把服务器192.168.18.251做地址映射

- - 买路由器干什么,“猫”就是一个“路由器”你们应该买一个交换机~~~
热心网友 时间:2023-10-12 01:09
太牛*了,寝室里用思科2600,佩服啊!
思科2600是专业路由器,不同于家用路由器,它没有WEB管理界面,初次使用需要用专用的console线缆连接,通过命令行进行配置,如果你们当中没有技术牛人,建议换成普通的家用路由器吧,太折腾了

这个要用思科专门的命令的。
