I completely rewrote netlab’s device configuration file generation during the New Year break. netlab Release 26.01 no longer uses Ansible Jinja2 functionality and works with Ansible releases 12/13, which are used solely for configuration deployment. I had to break a few eggs to get there; if you encounter any problems, please open an issue.

Other new features include:

• EVPN for VXLAN-over-IPv6
• The ‘skip_config’ node attribute that can be used to deploy partially-provisioned labs
• Lightweight netlab API HTTP server by Craig Johnson
• Rudimentary support for Citrix Netscaler by Seb d’Argoeuves

You’ll find more details (and goodies) in the release notes.
