Cisco ROUTE 2.0: Network Principles and Layer 2 Technologies

This course is included in our On-demand training solution.


Understanding the purpose of some of the commonly used Layer1 and Layer 2 technologies, as well as network protocols, is central to understanding how hosts communicate with one another. LANs have rapidly evolved into support systems that are critical to communications within an organization and it is important to understand how these systems operate. In this course you will learn about data transport methods, packet flows, and packet management for IPv4 and IPv6. You will also learn about Layer 2 technologies such as the Point-to-Point Protocol (PPP) and Frame Relay and their operations.

Target Audience

Anyone wishing to obtain real-world routing knowledge, and those that are considering CCNP and CCIP certification. This learning path’s discussion of routing could also benefit early CCIE Routing and Switching candidates. Students completing the ROUTE 2.0 learning path should have a solid foundation in routing fundamentals, Cisco IOS basics, and Cisco routing basics. Attending the ICND1 and ICND2 classes or having the CCNA certification will fulfill these expectations.



Expected Duration

90 min.
