思科锭缠愁颊路由器如何配置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 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 192.168.1.1 ?
<cr>
Router(dhcp-config)#default-router 192.168.1.1
Router(dhcp-config)#dns-server
Router(dhcp-config)#dns-server 8.8.8.8
Router(dhcp-config)#network
Router(dhcp-config)#network ?
A.B.C.D Network number in dotted-decimal notation
Router(dhcp-config)#network 192.168.1.0 ?
A.B.C.D Network mask
Router(dhcp-config)#network 192.168.1.0 255.255.255.0 ?
<cr>
Router(dhcp-config)#network 192.168.1.0 255.255.255.0
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：192.168.1.1 255.255.255.0 网关192.168.1.1；DNS:8.8.8.8;
PC>ipconfig /all
Physical Address................: 0030.A3A1.776B
IP Address......................: 192.168.1.1
Subnet Mask.....................: 255.255.255.0
Default Gateway.................: 192.168.1.1
DNS 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；
