Which VPN topology is also known as a hub-and-spoke configuration?

by Dominik

The so-called “hub-and-spoke configuration” is a colloquial name for a centralized VPN structure which uses a single tunnel to reroute traffic; one networking pivot to rule them all, whereby “rule” means host a secure, private party for security- and privacy-hungry connections.

Which doesn’t mean it’s limited to a single interface; if anything, a two-interface hub-and-spoke approach is arguably a more common sight in modern VPN topologies. Speaking of things encountered at a migraine-inducing level of frequency, a hub-and-spoke VPN setup can get really convoluted, really fast. And as everything from thermodynamics to social contract theory teaches us – complex systems like a team of network engineers tend to fail a whole lot more than simple things like their management by virtue of there being a significantly higher number of moving parts to account for.

What that means for hub-and-spoke topology enthusiasts is that their enthusiasm is bound to get curbed in the near future. And it’s not going to be pretty because it won’t take long for them to encounter an issue so obscure and inexplicable that even just documenting it requires MS-grade knowledge of a largely unrelated field. So, always proceed with caution when you encounter this infrastructural void.
