But what if I told you there were a way to determine whether or not an email is valid without resorting to regular expressions at all? The activation email is a practice that’s been in use for years, but it’s often paired with complex validations that the email is formatted correctly.

It’s surprisingly easy, and you’re probably already doing it anyway. If you’re going to send an activation email to users, why bother using a gigantic regular expression?

Hardware Switch Controller (HSC) component of overlay-gateway subsystem on VCS uses Virtual IP for Management and Control plane communications, namely for talking to NSX-v Controllers.

We don’t want specialist knowledge or talent to go to waste.

In our daily rush we sometimes lose sight of what management is all about: creating the best team for the job at hand.

They are also simpler to script configuration for, since we’re using the same IP address on all rbridges.

On other hand, we still need to configure IP routing within our VCS fabric.

This titbit will become relevant when figuring out why your Management/Control plane may not be working at a later stage, since VCS talks to NSX Controllers from this IP, and thus things like OVSDB would also be handled on the Associated rbridge.
