    Junipers Terraform Automation Framework (JTAF)

    We’re at a point in our POCs whereas we’re looking at how we deploy configs automagically. In the Juniper world, we have ansible, pyez and the new kid on the block: JTAF. All code/data referenced in this can be found in the github repo: https://github.com/cruse1977/blog-juniper-jtaf-example What is JTAF JTAF is a way of deploying Juniper…

  • Juniper ZTP on QFX

    Juniper ZTP on QFX

    We’ve been playing recently with automating a lot of the Juniper devices we’ve got to deploy, the latest fun being the Juniper equivalent with PXE: ZTP.

Step forward: automation, or specifically ansible. To do this, we’re not looking to ‘fully’ automate at this point. I’m still picking up ansible hence…

  • Cisco-like IPSLA on JunOS

    One of the more common CPE type things we use is IPSLA, often used when you want to prefer a certain circuit but there are many use cases. On JunOS, this uses two processes for this, Real Time Performance Monitoring, and IP Monitoring, to provide an ICMP probe, and an action based on probe results.…
