Today’s blog post is the first part of our #30DaysofJuniper information sharing campaign. For the past month, we have been posting daily tips on Juniper configurations to help novice and experienced engineers alike. This is our second campaign like this, as we completed another 30 day campaign sharing Cisco information about a month ago, #30DaysofCisco.

These campaigns were inspired by an awesome knowledge sharing campaign on Twitter that was created by Arielle Hale (@WhutTheHale) called #30DaysofThreads. Her goal was to get folks to share in-depth and key insights about topics they are familiar or passionate about to help empower others. Her campaign inspired us at J.B.C. to put together a Cisco network knowledge-sharing campaign, and after the success of that, we’ve followed up with a Juniper campaign.
