The Never-Ending "My Overlay Is Better Than Yours" Saga
I published a blog post describing how complex the underlay supporting VMware NSX still has to be (because someone keeps pretending a network is just a thick yellow cable), and the tweet announcing it admittedly looked like a clickbait.

Martin Casado quickly replied NO (probably before reading the whole article), starting a whole barrage of overlay-focused neteng-versus-devs fun.

VXLAN/EVPN vs VRF Lite
A little background information first.
When having a business requirement of tenancy, most solutions will tend to lean towards VRF. That is because VLANs require a distributed L2 environment, which comes with spanning tree, mlag and a whole other glut of inefficient network control plane protocols. Upleveling the infrastructure to L3 ends up requiring VRF technology to enforce tenancy.
Once you’ve settled on this feature as the solution for the business requirement, the next question is: How do I successfully deploy VRFs in a large distributed environment at scale, that also allows me to minimize the burden of management while still enforcing tenancy in all the important parts of my network? Most conversations surrounding this question will lead down two solution paths:
- VXLAN with EVPN
- VRF Lite
Definitions of VXLAN with EVPN and VRF Lite.
VXLAN with EVPN leverages VRFs at every border and leaf switch, while all the intermediate devices (ie. spines, super spines) only see the encapsulated VXLAN traffic, and hence do not need any VRF intelligence or visibility.
A VRF Lite solution is fundamentally simpler since it uses less moving parts. The thought of enabling the EVPN address family and encapsulating traffic into a VXLAN tunnel Continue reading

The Week in Internet News: CIA Had Encryption Backdoor for Decades
We’re watching you: The U.S. CIA secretly had an ownership stake in Swiss encryption company Crypto AG for decades and was able to read encrypted messages sent using the company’s technology, the Washington Post reports. West German intelligence agencies worked with the CIA. Forbes columnist Jody Westby called for a congressional investigation.
We’re watching you, part two: Meanwhile, Russia’s Federal Security Service has ordered some large Internet companies in the country to give it continuous access to their systems, the New York Times reports. The FSB has targeted more than 200 companies, including popular messenger service Telegram, social network VK. and classified advertisement website Avito.ru.
Big bucks for space-based Internet: Astranis, a satellite Internet startup focused on bringing service to underserved areas, has raised $90 million in new funding, Fortune says. The new funding will help Astranis deploy its first satellite, focused on providing Internet service in Alaska.
Not so fast: Satellites, however, have some downsides, according to a story on TheConversation.com. Satellites are vulnerable to cyberattacks, with hackers potentially able to shut them down or even turn them into weapons, the story suggests.

What’s the next logical automation step after you cleaned up device configurations and started using configuration templates? It obviously depends on your pain points; for Anne Baretta it was a network inventory database stored in SQL tables (and thus readily accessible from his other projects).
Notes
- I’m always amazed that we have to solve simple problems decades after the glitzy slide decks from network management vendors proclaimed them solved;
- I’m also saddened that it’s often really hard to get data out of a network management product;
