This is a basic ospf configuration lab using two routers. Using two routers ospf configuration have been done in this lab. I have used cisco Packet tracer software to demonstrate the ospf configuration. This if you are learning or preparing for ccna certification or ccna training then this lab is for you. Simple and to the point in just few simple steps.
I hope you can clearly see the OSPF Topology diagram drawn below. And now if you can see you can clearly analyse that there are total three routers in this topology table and total three networks.
