IPv6 in Enterprise , Should we still talk about it?

5 years ago Jeff Doyle and I recorded a podcast on IPv6 in Enterprise. We talked about IPv6 addressing plan , adaption and growth rate of IPv6 in Enterprise. In this post I would like to talk about IPv6 deployment status,  challenges and the possible business drivers in IPv6 and I will share my thoughts on …

Private VLANs with VXLAN

Got this remark from a reader after he read the VXLAN and Q-in-Q blog post:

Automation: Tools vs Languages

When it comes to expressing intent in automation workflows, there is validation in both using a task or workflow engine and also knocking it together using scripting in some language. I try not to get involved in tool or language wars, but quite honestly sometimes can’t help myself. I’ve even been known to throw fire on the fuel and get the marshmallows out.

Task & Workflow Engines

Sometimes a framework or tool can feel constrained and by design can force you to work in a way that is computable. Let’s take what Ansible or Mistral does. It has a set of ordered tasks, an entry point, some input variables that "flow" through the lists of tasks and some calls to some modules that deal with outputs. I can understand how network engineers don’t like some of these approaches because it feels like dynamic feedback is missing from the engineering. Testing through both verification and validation phases is supposed to replace that immediate dynamic feedback and it can take some time to get used to.

These kinds of automation tools require installation and also the correct modules for integration against the networking components. The tool build can also be automated and Continue reading
