Abstract:
   This document updates RFC5575 which defines a 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.  This draft specifices IPv4 traffic flow
   specificaitnos.  Other drafst specify , IPv6), MPLS addresses, L2VPN
   addresses, and NV03 encapsulation of IP addresses.  The information
   is carried via the BGP, thereby reusing protocol algorithms,
   operational experience, and administrative processes such as inter-
   provider peering agreements.

   There are applications of that encoding format: 1) automation of
   inter-domain coordination of traffic filtering, such as what is
   required in order to mitigate (distributed) denial-of-service
   attacks; 2) enable traffic filtering in the context of a BGP/MPLS VPN
   service, and 3) aid centralized control of traffic in a SDN or NFV
   context.  Some of deployments of these three applications can be
   handled by the strict ordering of the BGP NLRI traffic flow filters,
   and the strict actions encoded in the Extended Community Flow
   Specification actions.  This defines the first two applications.

   This document provides the definition of a BGP NLRI which carries
   traffic flow specification filters, and Extended Community values
   which encode the actions a routing system can take if a packet
   matches the traffic flow filters.  The specification requires that
   the BGP Flow Specification traffic filters follows a string ordering,
   and that the BGP Flow Specification Extended Communities actions are
   processed in a defined order.
