How to Implement and Configure the IS-IS Protocol Online Training

IS-IS stands for Intermediate System to Intermediate System. An intermediate system is any device that forwards data inside a network. The IS-IS protocol is a standardized way for network devices to communicate with one another (a protocol) and share information so that data can be routed more efficiently. The IS-IS protocol is a lot like a post office, helping network devices decide on the best routes for data to travel.

Implementing and configuring the IS-IS protocol typically involves providing devices with the necessary information to set up a communication network between them that can share addressing information efficiently. By setting certain parameters and defining addressing and topological information, configuring IS-IS is like creating a roadmap for data to travel within the network. Many network devices support IS-IS natively, but they're not automatically set up to use it out of the box.

Typically, the best audience for learning how to implement and configure the IS-IS protocol is experienced network professionals who work on particularly large, complex networks. IS-IS configuration is considered an intermediate to advanced skill, and it's not necessary on smaller networks. Experienced network administrators and network engineers who have experience with routing and infrastructure design will benefit the most from learning to configure the IS-IS protocol.

No, this course wasn't designed to prepare you for any certifying exams. This relatively short course starts off emphasizing a theoretical understanding of the IS-IS protocol. But the bulk of the course is hands-on practice configuring virtualized network devices in a variety of different situations and with multiple parameters for the IS-IS protocol. In terms of industry certs, these skills and knowledge are most applicable to the CCNP Service Provider

Typically no, implementing and configuring the IS-IS protocol isn't an entry-level skill or a requirement for any beginner network administrators. New network professionals have more pressing things to learn, like network fundamentals, basic troubleshooting and understanding the more common protocols like OSPF and EIGRP. That said, if you feel like you've got a strong grasp of networking and subnetting basics, starting with IS-IS could get you into advanced networking.
