Here you will find various 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 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.
Objective: In this lab, you will configure OSPF routing protocol between both routers. This will allow your routers to route packets so that all routers and all hosts will be able to reach (ping) each other. Once your configuration is complete, you will use basic techniques to test your network’s connectivity.
Hardware Requirements
- Two routers with one serial port and two FastEthernet or Gigabit ports
- One back to back DTE/DCE serial cable
- IOS version 12.x or later
- A PC running a terminal emulation program
- Cisco console kit
Setup
- Configure the cabling as shown in the network diagram
- If the routers have a startup-config, erase it and perform a reload of the routers.
