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. {[}STANDARDS-TRACK{]}}, }
