How to Configure DHCP on a Cisco Router

This topic we will look at how configure DHCP on a Cisco Router for client computers. First of all we need to enable DHCP service (by default DHCP service is enabled on Cisco Router).

And then we need to create DHCP pool name and IP pool:

Router1(config)# ip dhcp pool TEKBLOQ-POOL
Router1(dhcp-config)# network

Then we need to set up default gateway , dns servers, domain and lease period:

Router1(dhcp-config)# default-router
Router1(dhcp-config)# dns-server 
Router1(dhcp-config)# domain-name TEKBLOQ.COM
Router1(dhcp-config)# lease 8

If we have printer, server and etc on the this ip pool we need to exclude that ip addresses:

Router1(config)# ip dhcp excluded-address
Router1(config)# ip dhcp excluded-address

Here we see that we have excluded IP addresses : and

That all we need to configure DHCP server on Cisco router.
