Abstract

AS Path Prepending provides a tool to manipulate the BGP AS_Path attribute through prepending multiple entries of an AS. AS Path Prepending is used to deprioritize a route or alternate path. By prepending the local ASN multiple times, ASs can make advertised AS paths appear artificially longer. Excessive AS Path Prepending has caused routing issues in the Internet. This document provides guidance with the use of AS Path Prepending, including alternative solutions, in order to avoid negatively affecting the Internet.
