As the Internet continues to grow exponentially, the need for network engineers to build, maintain,
and troubleshoot the growing number of component networks also has increased significantly.
Because network troubleshooting is a practical skill that requires on-the-job experience, it has
become critical that the learning curve necessary to gain expertise in internetworking technologies be
reduced to quickly fill the void of skilled network engineers needed to support the fast-growing
Internet. IP routing is at the core of Internet technology, and expedient troubleshooting of IP routing
failures is key to reducing network downtime. Reducing network downtime is crucial as the level of
mission-critical applications carried over the Internet...
