Abstract

   To help reduce well-known threats against BGP including prefix mis-
   announcing and monkey-in-the-middle attacks, one of the security
   requirements is the ability to validate the origination AS of BGP
   routes.  More specifically, one needs to validate that the AS number
   claiming to originate an address prefix (as derived from the AS_PATH
   attribute of the BGP route) is in fact authorized by the prefix
   holder to do so.  This document describes a simple validation
   mechanism to partially satisfy this requirement.
