Introduction to Juniper

Introduction to Juniper

The Juniper Introduction series, available on YouTube, is a great way to learn Juniper’s network philosophy.

Many of us are familiar with networking in general, but perhaps we haven’t used Juniper’s platforms before. I learned on Cisco equipment and found it a bit intimidating to move to Juniper.

But it is possible! As long as you have some networking experience, you can use this course to go from never having seen Juniper devices, to becoming a Juniper specialist.

You could even pass the JNCIA Junos exam if you want!

Most videos include optional extras to help you to test your understanding. These include quizzes, labs, study notes, transcripts, and flashcards.

The video series is free to all. The extra content is an inexpensive bonus for Patreon subscribers.
