The ones I've used have simply injected more specific routes into my own local routing table to determine what path traffic takes to reach a specific destination.
That's pretty much all it does. The same way I use communities to do this based upon geography, or 500 other things [avoiding 1299 getting to certain networks]. The difference is now it's all manual. I wasn't advocating for allowing route optimizers to inject routes that escape your own ASN. I'm not sure how that became the topic.

You realise that this is not just what the problematic "route optimizers" do, right? And also not the problematic bit? -- Niels.
