Abstract

This document defines a Border Gateway Protocol Network LayerReachability Information (BGP NLRI) encoding format that can be usedto distribute (intra-domain and inter-domain) traffic FlowSpecifications for IPv4 unicast and IPv4 BGP/MPLS VPN services. Thisallows the routing system to propagate information regarding morespecific components of the traffic aggregate defined by an IPdestination prefix.

It also specifies BGP Extended Community encoding formats, which canbe used to propagate Traffic Filtering Actions along with the FlowSpecification NLRI. Those Traffic Filtering Actions encode actions arouting system can take if the packet matches the Flow Specification.

This document obsoletes both RFC 5575 and RFC 7674.
