A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Inter-Domain Routing of the IETF. Title : Methods for Detection and Mitigation of BGP Route Leaks Authors : Kotikalapudi Sriram Doug Montgomery Brian Dickson Keyur Patel Andrei Robachevsky Filename : draft-ietf-idr-route-leak-detection-mitigation-06.txt Pages : 24 Date : 2017-03-06 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.
