Here in this Lab i have shown how to configure a single Router to work as four DHCP SERVER.To show configuration i have used cisco packet tracer software here.This lab contains 1 Router, 4 switches and 8 computers.All four switches in this Lab are in different network and the computers in each network get their ip address through router using DHCP.Since ther are four network here,therefore we need create four different DHCP POOL on router to provide ip address to machines or computers located in four different networks.

Start Configuring Router:

Router>enable
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.

 

Configuration ON FA0/0 port :=>
————–

Now it’s time to assign ip address on router interfaces.

Router(config)#int fa0/0
Router(config-if)#ip address 1.0.0.1 255.0.0.0
Router(config-if)#no shut

Now configure or Create DHCP POOL to create DHCP Server on Cisco Router.

Here nik is the name of dhcp pool created.

 

Router(config-if)#ip dhcp pool nik
Router(dhcp-config)#network 1.0.0.0 255.0.0.0
Router(dhcp-config)#default-router 1.0.0.1
Router(dhcp-config)#exit

 

Configuration ON ETH0/0/0 PORT :=>
——————

Router(config)#int eth0/0/0
Router(config-if)#ip address 2.0.0.1 255.0.0.0
Router(config-if)#no shut

Now Create another POOL using below command:

Router(config-if)#ip dhcp pool knd
Router(dhcp-config)#network 2.0.0.0 255.0.0.0
Router(dhcp-config)#default-router 2.0.0.1
Router(dhcp-config)#exit

 

Configuration ON FA0/0 PORT :=>
—————–

Router(config)#int fa0/1
Router(config-if)#ip address 3.0.0.1 255.0.0.0
Router(config-if)#no shut

Router(config-if)#ip dhcp pool nikhil
Router(dhcp-config)#network 3.0.0.0 255.0.0.0
Router(dhcp-config)#default-router 3.0.0.1
Router(dhcp-config)#exit

 

Configuration on  ETH0/1/0 :=>
————–

Router(config)#int eth0/1/0
Router(config-if)#ip address 4.0.0.1 255.0.0.0
Router(config-if)#no shut

Now create another dhcp pool name nnn

 

Router(config-if)#ip dhcp pool nnn
Router(dhcp-config)#network 4.0.0.0 255.0.0.0
Router(dhcp-config)#default-router 4.0.0.1
Router(dhcp-config)#exit
Router(config)#

 

Assign hostname to the router :=>
—————————

Router(config)#hostname R1
R1(config)#
