Abstract:

   Autonomous System Provider Authorization (ASPA) defines an RPKI-based
   methodology to validate the AS_PATH of BGP routes based on a global
   Customer-to-Provider (C2P) relationship model.  However, in
   commercial Internet routing, two Autonomous Systems (ASes) may
   establish distinct business relationships across different
   geographical regions or interconnection points (e.g., Customer-to-
   Provider in one region, but Peer-to-Peer in another).  Such
   regionalized or hybrid AS-relationships can lead to incorrect ASPA
   validation results (e.g., false "Valid" attestation for a route
   propagated over a P2P link).  This document analyzes the
   vulnerabilities caused by regionalized AS-relationships and proposes
   mechanisms to incorporate regional granularity into ASPA objects and
   verification procedures.
