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:;

DHCP: GW:;

配置如下：

outer(config)#ip dhcp pool DHCPLIST

Router(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 options

Router(dhcp-config)#def

Router(dhcp-config)#default-router ?

Router(dhcp-config)#default-router

Router(dhcp-config)#dns-server

Router(dhcp-config)#dns-server

Router(dhcp-config)#network

Router(dhcp-config)#network ?

A.B.C.D Network number in dotted-decimal notation

Router(dhcp-config)#network ?

A.B.C.D Network mask

Router(dhcp-config)#network ?

Router(dhcp-config)#network

Router(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： 网关；DNS:;

PC>ipconfig /all

Physical Address................: 0030.A3A1.776B

IP Address......................:

Subnet Mask.....................:

Default Gateway.................:

DNS Servers.....................:

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；
