The featured webinar in September 2017 is the Ansible for Networking Engineers webinar, and in the featured videos you'll learn what Jinja2 is and how you can use it to generate network device configurations with Ansible.

Plenty of new stuff was added to the Ansible for Networking Engineers online course and webinar since the last update.

Fun things first: I needed adjustable check mode behavior and change tracking in some playbooks, and documented these features in two new videos (online course and webinar).

It all started with a realistic response I got to my automation and orchestration blog post (here’s a unicorn-driving-a-DeLorean one in case you missed it):

Maybe you could also add the “intent-based network” which is also not so far from orchestration?

It got me thinking. The way I understand intent-based whatever, it’s an approach where I tell a system what I want it to do, not how to do it.

A network engineer interested in attending the Building Network Automation Solutions online course sent me this question:

Does the course cover only Ansible, or does it also cover other automation tools like Python?

The course focuses on how you’d build a network automation solution. Selecting the best tool for the job is obviously one of the major challenges, and so one of the self-study modules describes various automation tools and where you could use them to build a full-blown solution.

A network architect working for a system integrator sent me a number of questions along the lines of “what would be an interesting alternative to pursuing another CCxE certification?”

He wrote:

One of the use cases we covered in Network Automation Use Cases webinar is a fully-automated data center fabric deployment. Dinesh Dutt (Cumulus Networks) started this section with an overview of challenges you might face in data center fabric deployments.

One of the engineers going through my Ansible for Networking Engineers online course sent me this question:

In the Introduction section, you mention a use case of upgrading software. Do you have an example playbook?

Unfortunately, I don’t. Upgrading software is one of those things that’s almost impossible to simulate in a virtual lab.

Some networking practitioners start their network automation journey with the Python or Ansible dilemma. Engineers and architects usually want to understand the bigger picture first, and figure out the potential showstoppers and roadblocks. One of them left this feedback on the Network Automation 101 webinar:

A must-have overview of fundamental Network Automation concepts. I wouldn't face an automation project without understanding these concepts first.

In mid-July dr. Olivier Bonaventure (one of the unsung networking heroes who’s always trying to address real-life problems instead of inventing unicorn solutions in search of a problem) sent an email to v6ops mailing list describing how they teach networking.

Short summary for differently-attentive:

I’ve added two new case studies to Ansible for Networking Engineers online course:

Create network diagrams from LLDP information playbook focuses on creating a single summary report based on information from numerous devices (and the report just happens to be network diagram in DOT format).
