Cisco Labs OSPF

This book provides multiple practical lab scenarios for configuring the OSPF protocol on Cisco IOS
It covers a wide range of topics, starting from basic OSPF configuration to more advanced setups, including OSPF over VLANs, OSPF over VPNs, multi-area networks, and configuration of stub, totally stubby, not-so-stubby, and totally not-so-stubby areas, route summarization, route redistribution, virtual links, and the configuration of VRFs using multiple OSPF instances
This book is designed so that you can read each lab independently.  The labs are not dependent on one another, so you don't need to complete them in sequential order. Simply select the scenario you wish to explore and start reading immediately
Even though this book doesn't cover the theoretical side of the OSPF in detail, it provides a quick overview of the protocol to help you understand the concepts behind each lab and the purpose of the configurations, so that you can follow, understand, and complete the labs with confidence
