Re: 16-bit ASN kludge
I don't see non-transit ASN leakage as any greater issue than current private ASN leakage. However, I do see the ability to use non-transit ASNs to multihome end sites with provider independent addresses and allow better aggregation as a good thing. In this case, leakage would only have the same consequences as doing things the way we do them now. I don't see a real downside.

Essentially, any non-transit network would have it's non-public ASN retranslated NAT-style by upstream transit network border routers. Only the border routers would have to be changed. They would have to differentiate between public ASN X and non-public ASN X (same number) based on the which side of the router the ASN was learned from.So given the lack of trouble with NAT sites leaking rfc1918 addresses, you foresee no problems with sites accidentally leaking the non-public ASN's, right?
