The IESG has approved the following document: - 'Guidance to Avoid Carrying RPKI Validation States in BGP Path Attributes' (draft-ietf-sidrops-avoid-rpki-state-in-bgp-11.txt) as Best Current Practice
This document is the product of the SIDR Operations Working Group. The IESG contact persons are Mahesh Jethanandani and Mohamed Boucadair. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-sidrops-avoid-rpki-state-in-bgp/ Technical Summary This document provides guidance to avoid carrying Resource Public Key Infrastructure (RPKI) derived validation states in Border Gateway Protocol (BGP) Path Attributes whose change triggers a BGP UPDATE being sent across external BGP (EBGP) sessions. Annotating routes with BGP Path Attributes carried across EBGP sessions signaling validation states may cause needless flooding of BGP UPDATE messages through the global Internet routing system, for example when Route Origin Authorizations (ROAs) are issued, or are revoked, or when RPKI-To-Router sessions are terminated. Operators should ensure RPKI-derived validation states are not signaled in BGP Path Attributes whose change triggers a BGP UPDATE being sent across EBGP sessions. Specifically, operators should not associate Prefix Origin Validation state with BGP routes using any form of BGP Communities carried across EBGP session. Working Group Summary & Document Quality Working Group Last Call has shown a broad support for this document.
