Abstract:
   RFC 7908 provides a definition of the route leak problem, and also
   enumerates several types of route leaks.  This document first
   examines which of those route-leak types are detected and mitigated
   by the existing origin validation (OV) [RFC 6811].  It is recognized
   that OV offers a limited detection and mitigation capability against
   route leaks.  This document specifies enhancements that significantly
   extend the route-leak prevention, detection, and mitigation
   capabilities of BGP.  One solution component involves intra-AS
   messaging from ingress router to egress router using a BGP Community
   or Attribute.  This intra-AS messaging prevents the AS from causing
   route leaks.  Another solution component involves carrying a per-hop
   route-leak protection (RLP) field in BGP updates.  The RLP fields are
   proposed to be carried in a new optional transitive attribute, called
   BGP RLP attribute.  The RLP attribute helps with detection and
   mitigation of route leaks at ASes downstream from the leaking AS.
