I don't recall saying that, or anything about route selection. I don't want all backbone routers (or any of them, for that matter) ignoring Update messages (or worse, propagating the announcements) with malformed AS_PATH attributes when they should be returning a NOTIFY and closing the BGP session.
You said you wanted routers that followed the RFC. The RFC does not mention list AS_PATH length as a route selection criteria. I have been told that the draft for the next rev specifically prohibits using AS_PATH length as a route selection criteria. I kinda like using AS_PATH length. It's not perfect - and I'm definitely open to suggestions - but for now it's working. And changing that in today's environment would be ... monumental to say the least. OTOH, I completely agree that the routers should have *not* passed on malformed announcements, and behaving improperly to certain errors.
