Dear WG,

Here's the 03 version update to the route leak detection (RLD) using BMP draft. 

We proposed a RLD TLV (a business relation representation) to be attached to the BMP adj-rib-in/adj-rib-out at an AS's ingress/egress nodes. With the allowance of TLV support in the BMP Route Monitoring Message (draft-lucente-bmp-tlv), we expect a RLD TLV type to be assigned. The BMP server can use the per-route RLD TLVs to detect the existence of route leaks that happen within the local AS. It does not do leak prevention or mitigation, however, operators can base on the detection results to take further actions, such as check configurations. 

In addition, as a possible complementary action against route leaks to draft-ietf-idr-bgp-open-policy-05 (intra-AS route leak prevention) and draft-ietf-grow-route-leak-detection-mitigation-00 (cross-AS route leak detection and mitigation), more details about the differences/coordination are discussed in the draft. 

We believe this simple, straightforward idea can be helpful for either self-checking of leaks or assisting checking of leaks in other ASes (with the settlement of draft-ietf-grow-route-leak-detection-mitigation-00). We'd like comments from the WG.

Thank you.

Yunan

Abstract:
   According to RFC7908 [RFC7908], Route leaks refer to case that the
   delivery range of route advertisements is beyond the expected range.
   For many current security protection solutions, the ISPs (Internet
   Service Providers) are focusing on finding ways to prevent the
   happening of route leaks.  However, the real-time route leak
   detection if any occurs is important as well, and serves as the basis
   for leak mitigation.  This document extends the BGP Monitoring
   Protocol (BMP) [RFC7854] to provide a routing security scheme
   suitable for ISPs to detect BGP route leaks at the prefix level.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
