Not really sure how much use its going to be in the real world, unless you work for a university and they implement it all in opendaylight/NOX or similar.
Heck I just did a 2 day primer from SDN essentials and the case study they used (Sanford IIRC?) for a pure openflow implementation - they used openflow purely for L2 forwarding, they kept traditional L3 LOLOLOL.


Heck even here, they talk about using openflow/opendaylight only for access, L3 routed core still.

All the big commercial products may have some openflow in there somewhere but knowing how to mess around with flow tables is not really going to help you setup ACI, NSX, Contrail, or heck even Ansible provision some VXLANs across a leaf-spine Arista or Cumulus setup.

Yep... pretty spot-on there Winter.  Initially some folks blew OF off... but it's alive and well particularly in academia... so there has to be some support for it, but I'd say it's far from mainstream.  I have yet to have to support it for a customer in the now almost 2 years I've been doing this.  Ansible on the other hand, now that's funny you mention it because I somewhat recently fell in love with it (Wrote an article on EOS central - https://eos.arista.com/my-journey-with-ansible-and-arista/), and I'm working two projects right now with two separate groups from the same customer looking at automation with Ansible - and it could turn into three (A pretty wild concept of TapAggregation with VXLAN for tunneling, and automating the entire thing across three DCs with Ansible and other stuff; in other words, an automated monitoring network where you can tap anywhere, any time).
