The IESG has approved the following document: - 'Mitigating Negative Impact of Maintenance through BGP Session Culling' (draft-ietf-grow-bgp-session-culling-05.txt) as Best Current Practice This document is the product of the Global Routing Operations Working Group. The IESG contact persons are Warren Kumari and Benoit Claise. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-grow-bgp-session-culling/ Technical Summary This document outlines an approach to mitigate negative impact on networks resulting from maintenance activities. It includes guidance for both IP networks and Internet Exchange Points (IXPs). The approach is to ensure BGP-4 sessions affected by the maintenance are forcefully torn down before the actual maintenance activities commence. Basically, this suggests tearing down the BGP session (so it can reconverge) before breaking the data-plane. This is documenting a well known, and widely used (but not widely enough!) technique. Working Group Summary Nothing of note in the WG process. Document Quality This is documenting (with examples!) how to perform a operational practice which minimizes breakage. It is a simple, but effective technique. Personnel Shepherd: Chris Morrow (christopher.morrow@gmail.com) Responsible AD: Warren Kumari (warren@kumari.net)
