思科路由器如何配置DHCP实例

思科路由器如何配置DHCP实例?今天给大家分享一下思科路由器配置成DHCP服务器;由于实例很简单,于是精简单讲解;如图示:如图示：路由0：F0/0:59.40.78.185/28;DHCP:192.168.1.0/24 GW:192.168.1.1;配置如下：outer(config)#ip dhcp pool DHCPLISTRouter(dhcp-config)#? default-router Default routers dns-server Set name server exit Exit from DHCP pool configuration mode network Network number and mask no Negate a command or set its defaults option Raw DHCP optionsRouter(dhcp-config)#defRouter(dhcp-config)#default-router 192.168.1.1 ? Router(dhcp-config)#default-router 192.168.1.1Router(dhcp-config)#dns-serverRouter(dhcp-config)#dns-server 8.8.8.8Router(dhcp-config)#networkRouter(dhcp-config)#network ? A.B.C.D Network number in dotted-decimal notationRouter(dhcp-config)#network 192.168.1.0 ? A.B.C.D Network maskRouter(dhcp-config)#network 192.168.1.0 255.255.255.0 ? Router(dhcp-config)#network 192.168.1.0 255.255.255.0Router(dhcp-config)#end如上配置所示：可以看到DHCP配置起来只有几步，很容易实现；那么现在让我们来验证；在路由器通过命令：show ip DHcp binding可以查到一个客户端已经获取了IP地址：192.168.1.1 255.255.255.0 网关192.168.1.1；DNS:8.8.8.8;PC>ipconfig /allPhysical Address................: 0030.A3A1.776BIP Address......................: 192.168.1.1Subnet Mask.....................: 255.255.255.0Default Gateway.................: 192.168.1.1DNS Servers.....................: 8.8.8.8由此思科路由器的DHCP服务已经设置成功；总结：有些路由器DHCP功能默认是关闭的，可以通过：service DHCP 开启DHCP服务，然后再做配置；其实原理都一样，配置DHCP几个步骤：建议DHCP分配池，网关，分配的IP段，DNS；就这么几个设置；
