@bms48 @KathyReid This is getting way into the weeds for something that was initially an idle thought, but yes, you need the substrate. There's different types of substrate, though. Just because you're replacing something at the network layer doesn't mean you can't have a janky gateway connecting to the rest of the internet, for instances where you really need to get to Amazon or whatever. It also provides the option of dropping old cruft from protocols (at the risk of 2nd system effect).

@Andres4NY @KathyReid This is why Ph.D is sometimes jokingly referred to as "the too-far-thing-taking". Yeah, I used to knock up tunnels to AWS over IPSEC with pfSense for a rather annoying fintech client. They ended up in Duo Security's old serviced office space (with a smelly, busy toilet) after Duo found somewhere proper in London E1. But overlays are overlays, and you always pay a tax. Part of the motivation behind segment routing is to get rid of that tax for much cruft. George Varghese FTW
