BMP for BGP Route Leak Detection
draft-gu-grow-bmp-route-leak-detection-04
Abstract
According to RFC7908 [RFC7908], Route leaks refer to the 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 BGP [RFC4271] 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.
