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 Autonomous
System (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.
