I needed to do some testing of Juniper Contrail API calls, and for that I could use some Juniper switches controlled by Contrail. As Juniper has recently launched a virtual vEX image, I figured I’d give it a go. Below are build instructions for creating a vagrant box for Juniper vEX. Tools Vagrant: Vagrant from Hashicorp. Vagrant is a tool for building and managing virtual machine environments in a single workflow.

I needed to replicate a Juniper SRX firewall to create and test a BGP config for a customer. I could have done this in GNS3/EVE-NG or some other virtual enviornment, but I find that Vagrant/Libvirt gives me the most usability when trying to reuse a setup over time, such as for automated testing. So with that goal in mind, I needed to create a vagrant box of Juniper’s vSRX firewall, but specifically for use with libvirt.
