Protocol Suites and the Internet Layer of IP

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


In the past there were many protocol suites to choose from including IPX, OSI, IPv4, and AppleTalk. Today’s choices are narrower with IPv4 and IPv6 being the predominant network models. In this course, you’ll learn about the basics of network protocol models and the Internet layer of both IPv4 and IPv6. Exposure to these protocols will lay the foundation for many technologies and represents crucial information to the network engineer. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.

Target Audience

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.



Expected Duration

90 min.
