build own cisco lab

could any body tell me please which hardware do i need to build the cisco lab for prepare CCNP as well as CCIE

Your best bet bud is to check out the free Network Simulator known as GNS3. It is FREE. Go to www.gns3.net and you will find everything you need.

Or if you still want real hardware, check out www.ciscokits.com/index.php

They have kits for everything so you can see what they think you need for a specific test and then shop around if need be.
