    One major advantage to NSX-T is that Edge Transport Nodes (ETNs) are transitive Transitivity (Wikipedia) (Consortium GARR) is an extremely important concept in network science, and in computer networking. In simple terms, a network node (any speaker capable of transmitting or receiving on a network) can have the …

    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. Solution Overview VyOS is a fantastic platform, with a ton of …

    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 …
