September 25, 2016: Yesterday was the last day to take the ICND2 v2 exam. Our CCNA v2 specific material has been removed and now all of the CCNA material is for the updated v3 exam. Also, more CCNP Route videos have been added.

September 21, 2016: More CCNP Route videos have been added.

September 11, 2016: After passing the CCNA exam many of you have asked us to release CCNP material, and so here you go! There is quite a bit of CCNP material to cover so it's still a work in progress, but we'll continue to release new material as it's ready. The first 3 sections of the CCNP Route videos are live now, with more coming soon. Also by user request, we have added a filter on the Video and Lab pages so you can see only the lessons that correspond to your particular exam.

August 20, 2016: The CCNA material has been updated for the new CCENT/CCNA version 3.0 of the exams (ICND1/ICND2/CCNAX). Note, if you are planning to take ICND2 v2.0, the last day to take the exam is Sep 24, 2016. Specific videos for v2 and v3 are notated on the video page.
