Here is one of our Cisco CCNA 200-301 labs we have decided to provide FREE to you! These labs were created and we felt they were not advanced enough for our partner’s CCNA Lab Workbook. They are either not complex enough, do not cover multiple concepts, or do not have enough commentary explaining what we want to accomplish in each lab and why you are doing each step. These labs are basically just simple configurations and not what we would really call labs. Why? Because they do not really help you learn.
Free Cisco CCNA v7 Lab – BGP – CertificationKits.com
Objective:
In this lab you will configure a complex environment consisting of BGP and OSPF. You will then run basic testing commands to verify all links and protocols are working properly.
Hardware Requirements:
· Two Cisco routers with one serial port
· Two Cisco routers with two serial ports
· Cisco IOS 12.0 or higher
· A PC running a terminal emulation program
· Three back to back DTE/DCE serial cables
· Cisco console kit
