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.
This document defines protocol extensions and procedures for BGP Provider/Customer Edge router iteration in BGP/MPLS IP VPNs. These extensions and procedures have the objective of making the usage of the BGP/MPLS IP VPN transparent to the customer network, as far as routing information is concerned.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
