    As is probably obvious from the sidebar, I'm pretty enthusiastic about IPv6 - for quite a few reasons, not least of which is implementing a new Layer 3 protocol after guys like Vint Cerf already did most of the cool stuff. However, I didn't want to simply complete this task - most people complete all of these tasks …

    I have mentioned in a previous blog post that I'm not using any ACLs on my tunnel broker VM This is usually pretty bad, but again, we can get those protections outside of the VM - I'm using this to prove out how NSX-T can provide utility in this situation.

    First off, let's cover what's been built so far: To set up an anycast vIP in NSX-T after standing up your base infrastructure (already depicted and configured), all you have to do is stand up a load balanced vIP at multiple sites. NSX-T takes care of the rest. Here's how: Create a new load balancing pool. Create a new …

    Before getting started, let's cover what different IP message types exist in a brief summary, coupled with a "day in the life of a datagram" as it were. Unicast: One source, one well-defined destination. Most network traffic falls into this category. Mayfly perspective: Source device originates packet, and …

    Now that the primary infrastructure components for NSX-T are in place, it is now possible to build-out the actual functions that NSX-T is designed to provide. A friendly suggestion, make sure your Fabric is healthy before doing this: NSX-T differs from NSX-V quite a bit here. Irregular topologies between edge routers …

    Since NSX-T 2.5 just came out, it's about time to do a full rebuild and getting started guide. NSX-T differs greatly from NSX-V in that the initial setup is quite a bit more complicated and doesn't have many guardrails or direct paths to initial set-up. We'll be skipping the appliance deployment, because if you have …

    Now that NSX-T Datacenter 2.5 is downloadable, it's time to try this out in my home lab. First things first, if you log in more than 90 days out, you'll be locked out of the appliance completely. If you make any changes the normal linux way (passwd and chage) the appliance will automatically revert it in about a …

    25 Gigabit implementations First of all - anyone who assumes they think Layer 1 is simple is wrong. That being said, 25G/50/100G/QSFP28 services are different beyond simply being 2.5x faster than 10G. 802.3by (or 25 Gig for those who use it): Full-Duplex is mandatory.
