           IRR & Routing Policy Configuration Considerations
         <draft-ietf-grow-irr-routing-policy-considerations-02>

Abstract

   The purpose of this document is to catalog past issues influencing
   the efficacy of Internet Routing Registries (IRR) for inter-domain
   routing policy specification and application in the global routing
   system over the past two decades.  Additionally, it provides a
   discussion regarding which of these issues are still problematic in
   practice, and which are simply artifacts that are no longer
   applicable but continue to stifle inter-provider policy-based
   filtering adoption and IRR utility to this day.
