Comparing with my original review (-18) the authors have addressed my concerns. There is one remaining, probably smaller, issue: The Security Considerations section states: "In order to mitigate the risk of the diversion of traffic from its intended destination, existing BGPsec solution could be extended and supported for this SAFI." - was this meant to say "existing BGPsec solutions" or "the existing BGP solution"? Also, it isn't clear how BGPsec should be extended - and if it would provide any substantial benefit over the mechanisms described herein (the remainder of this paragraph states: "The restriction of the aplicability of this SAFI to its intended well-defined scope limits the likelihood of traffic diversions. Furthermore, as long as the filtering and appropriate configuration mechanisms discussed previously are applied diligently, risk of the diversion of the traffic is significantly mitigated.").
