BGP Flowspec mechanism (BGP-FS) [RFC8955] [RFC8956]propogates both traffic Flow Specifications and Traffic Filtering Actions by making use of the BGP NLRI and the BGP Extended Community encoding formats. This document specifies a new BGP-FS component type to support AS- level filtering. The match field is the origin AS number of the destination IP address that is encoded in the Flowspec NLRI. This function is applied in a single administrative domain.
