(Replying to the correct thread now)



I’ve read the draft, focusing mostly on section "6. BGP Security Threats Addressed by SPL-ROV" -- the problems SPL wants to solve that are not solved by ROA and ASPA.



I see threat 4 as the real concern here without a widespread ASPA adoption.  Just for that I support the adoption.

It is especially important to solve thread 4 if we are recommending adding ASNs to ROA for direct server return cases for SAV purposes (for algorithms like BAR-SAV).





I do have questions about the rest of the threats mentioned.



Threats 1, 2, and 5 are "If someone is forging some announcements, do not let them blame it on my AS".  Is this “AS reputation” a big concern?  Protecting against threats 1 and 5 does not help protect any packets from being misrouted/hijacked (and no IP space is being hijacked in threat 2 to begin with), since the malicious AS can pick any other ASN as the origin.  It is just about not letting my AS show up as the "origin", right?



Threats 2 and 4 can be mostly solved by ASPA (but only if providers also maintain ASPA entries, transitively, so it is a tall order).



Threat 3 can be solved by ROA, but that may be not under AS’s control.  It is really an AS protecting against its own mistakes.
