The primary objective of this book is to provide elaborate guidance for troubleshooting Internet Protocol (IP) routing problems on Cisco routers. In this regard, the subsequent text covers well-known routing protocols such as the following:

• Open Shortest Path First Protocol (OSPF)

• Integrated Intermediate System-to-Intermediate System Protocol (IS-IS)

• Border Gateway Protocol (BGP)

• Protocol Independent Multicast (PIM) for multicast routing
