Hi Alvaro,

On Feb 21, 2020, at 7:47 AM, Alvaro Retana <aretana.ietf@gmail.com<mailto:aretana.ietf@gmail.com>> wrote:

431    o  It can be determined that the IP address in the sub-TLV's address

433       its Autonomous System subfield.  (See section Section 13 for
434       discussion of one way to determine this.)

[major] "one way"  I hope that it is the MTI way -- otherwise, the
determination of the sub-TLV being malformed is not deterministic.

ISTM (I am just guessing though) that the “it can be determined” language was finely crafted to avoid this exact objection. It makes the entire clause optional.

If we try to make determination of IP address belonging to a given AS mandatory, I think we are opening a can of worms, since although RPKI deployment has made a lot of progress, it’s far from universal. I think we are better off leaving this as written, IMO.
