Learn how to configure multiple dhcp server on single router.See the below lab diagram and learn how to configure more than one DHCP pool on a router.After reading this article you will be able to configure multiple dhcp server on a single router.

 

Here in this lab we have configured two dhcp server on both routers.Hence this article will help you understand how to configure multiple dhcp server on single router.
