This document defines a new Border Gateway Protocol Network Layer
Reachability Information (BGP NLRI) encoding format that can be used
to distribute traffic flow specifications.  This allows the routing
system to propagate information regarding more specific components of
the traffic aggregate defined by an IP destination prefix.

Additionally, it defines two applications of that encoding format:
one that can be used to automate inter-domain coordination of traffic
filtering, such as what is required in order to mitigate
(distributed) denial-of-service attacks, and a second application to
provide traffic filtering in the context of a BGP/MPLS VPN service.

The information is carried via the BGP, thereby reusing protocol
algorithms, operational experience, and administrative processes such
as inter-provider peering agreements.  [STANDARDS TRACK]
