MM: Good idea. How about a simple statement added to the Alternatives to AS Path Prepending section: “Coordinate with neighboring ASes that can apply inbound policies (e.g., route-maps) to achieve routing preferences without requiring AS path prepending.” Thanks, Mike Thanks, Saumya.

It is a work item of the Global Routing Operations (GROW) WG of the IETF. Title: AS Path Prepending Authors: Mike McBride Doug Madory Jeff Tantsura Robert Raszuk Hongwei Li Jakob Heitz Gyan Mishra Name: draft-ietf-grow-as-path-prepending-16.txt Pages: 13 Dates: 2025-07-07 Abstract: Autonomous System (AS) path prepending is a tool to manipulate the BGP AS_PATH attribute through prepending one or more Autonomous System Numbers (ASNs). AS path prepending is used to deprioritize a route in the presence of a route with a shorter AS_PATH. By prepending a local ASN multiple times, ASes can make advertised AS paths appear artificially longer. However, excessive AS path prepending has caused routing issues in the Internet. This document provides guidance for the use of AS path prepending, including alternative solutions, in order to avoid negatively affecting the Internet.
