   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,to the internet community, with how best to utilize AS Path
   Prepending in order to avoid negatively affecting the internet.
