You begin the course by understanding network fundamentals, discussing topics such as the OSI Model, switch and router functionality, and cabling standards. From there, you will move quickly into understanding the differences between IOS and IOS-XR (Cisco’s service provider-specific OS), configuration of routing protocols in both IPv4 and IPv6, network services, and device management.
this course does move faster than most since Cisco assumes most individuals aspiring to work in a service provider role have some previous background in a technology arena. In addition, Jeremy has created a “reduced schedule” of videos for those already competing the CCENT (ICND1) or CCNA (ICND2) courses.
