In this hands-on lab we will build a virtual small business network and configure our routers to use the routing protocol OSPF. We will explore its many features and requirements for operation. We will configure everything on the command-line (one command at a time), and then learn a variety of show commands useful for verifying our configurations and for troubleshooting. Like all of my courses in the "Let's Learn" series, we will use Packet-Tracer as our simulated network environment (available free from Cisco).
Note: this is a beginner's introduction to OSPF meant to help you with the basics so you can understand the manuals better.
