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.
