The IESG has approved the following document: - 'Problem Definition and Classification of BGP Route Leaks' (draft-ietf-grow-route-leak-problem-definition-06.txt) as Informational RFC This document is the product of the Global Routing Operations Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-grow-route-leak-problem-definition/ Technical Summary A systemic vulnerability of the Border Gateway Protocol routing system, known as 'route leaks', has received significant attention in recent years. Frequent incidents that result in significant disruptions to Internet routing are labeled "route leaks", but to date we have lacked a common definition of the term. In this document, we provide a working definition of route leaks, keeping in mind the real occurrences that have received significant attention. Further, we attempt to enumerate (though not exhaustively) different types of route leaks based on observed events on the Internet. We aim to provide a taxonomy that covers several forms of route leaks that have been observed and are of concern to Internet user community as well as the network operator community. Working Group Summary This draft got significant review/discussion in the WG, with 5 revisions and agreement in the group on the focus and direction/content of the draft. Document Quality There are no implementations of a protocol for this, this document is a taxonomy of route leak types/causes/etc. Personnel Shepherd: Chris Morrow AD: Joel Jaeggli
