Thanks, Mark. So the discrepancy between what's being advertised (/21 vs /22) shouldn't cause any issues? That's the part I got a bit confused about. I don't see how it would, but I wanted to make sure.
Longest match always wins... so provided your /22's are in the global table, traffic will follow the path toward them before the /21 is preferred. So, for example, if the upstream to whom you are sending the /21 doesn't do anything about how they learn the /22 from another source, (for their network) they will also send traffic back to you via the /22 path. This may or may not be preferred by you, or them. I suppose that's the main thing to think about. Mark.
