Gns3 lab: Configure dhcp on cisco router

CONFIGURE DHCP ON CISCO ROUTER

DESCRIPTION 

[+] In this tutorial we learn how to configure the DHCP to create a small testing lab.
[+] First we create a network using one router and virtual machine.
[+] Second we configure the interface f0/0, see this post:
link: http://networkingdna.blogspot.in/2015/06/configure-telnet-on-cisco-router.html
[+] Third we configure the dhcp pool.
[+] Fourth from the Linux machine, we check the connectivity between linux machine and router.
[+] Below is the lab setup image.



HOW TO CONFIGURE DHCP 

STEPS

R1(dhcp-config)#ip dhcp pool networkingdna
R1(dhcp-config)#network 10.0.0.0
R1(dhcp-config)#dns-server 10.0.0.1
R1(dhcp-config)#default-router 10.0.0.1
R1(dhcp-config)#exit

Below is the image for more help-

ENABLE DHCP SERVICE 

Usually DHCP service is enabled by default. But in case if you want to start and stop  DHCP service you can use this command.

To Enable DHCP
R1(dhcp-config)#service dhcp

To Disable DHCP 
R1(dhcp-config)#no service dhcp

ON LINUX MACHINE 

• Observe DHCP automatically assigned the ip address to the linux machine.
• To verfiy the connectivity we ping the router address.
• See the below image for more details:
