Very substantial changes made from -09 to -10 version:
- Changes in the semantics of the RLP mechanism and the detection-mitigation algorithms
- In the draft, we're proposing to use BGP Large Community (transitive) to carry info about RLP
* However, we are looking for WG feedback about the options -- Regular Community vs. Large vs. Extended?
* See slides 19-24 for some details on these options (link to the slides below).
Authors' Team Discussion Slides may be helpful to see helpful graphics, scenario analyses:

Looking forward to your comments. Thanks.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Inter-Domain Routing WG of the IETF.
Title : Methods for Detection and Mitigation of BGP Route Leaks
Authors : Kotikalapudi Sriram
Alexander Azimov
Filename : draft-ietf-idr-route-leak-detection-mitigation-10.txt
Pages : 11
Date : 2018-10-22
Abstract:
Problem definition for route leaks and enumeration of types of route
leaks are provided in RFC 7908. This document describes a solution
for detection and mitigation route leaks which is based on conveying
route-leak protection (RLP) information in a Border Gateway Protocol
(BGP) community. The RLP information is carried in a new well-known
transitive BGP community, called the RLP community. The RLP
community helps with detection and mitigation of route leaks at ASes
downstream from the leaking AS (in the path of the BGP update). This
is an inter-AS (multi-hop) solution mechanism. This solution
complements the intra-AS (local AS) route-leak avoidance solution
that is described in ietf-idr-bgp-open-policy draft.
