The industry standard concepts of Adj-RIB-Out & MRAI seem extremely relevant to some of the claims made in this *checks notes* paper-that-also-promotes SCION (??!!). The paper's authors could not entirely avoid commenting on MRAI, but in a brief paragraph they stated: """MRAI could theoretically mitigate the BGP Vortex attack by slowing down route oscillations""". In my opinion the lede is being buried a bit here: if it is argued there is a potential problem, then in MRAI there is a potential and deployable solution, that'll work on quite a few platforms! Why not just set MRAI to something very small, like 1 or 2 seconds, on systems that support it, and call it a day?
