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.}, }
