A new Request for Comments is now available in online RFC libraries. RFC 7752 Title: North-Bound Distribution of Link-State and Traffic Engineering (TE) Information Using BGP Author: H. Gredler, Ed., J. Medved, S. Previdi, A. Farrel, S. Ray Status: Standards Track Stream: IETF Date: March 2016 Mailbox: hannes@gredler.at, jmedved@cisco.com, sprevidi@cisco.com, adrian@olddog.co.uk, raysaikat@gmail.com Pages: 48 Characters: 113130 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-idr-ls-distribution-13.txt URL: https://www.rfc-editor.org/info/rfc7752 DOI: http://dx.doi.org/10.17487/RFC7752 In a number of environments, a component external to a network is called upon to perform computations based on the network topology and current state of the connections within the network, including Traffic Engineering (TE) information. This is information typically distributed by IGP routing protocols within the network. This document describes a mechanism by which link-state and TE information can be collected from networks and shared with external components using the BGP routing protocol. This is achieved using a new BGP Network Layer Reachability Information (NLRI) encoding format. The mechanism is applicable to physical and virtual IGP links. The mechanism described is subject to policy control. Applications of this technique include Application-Layer Traffic Optimization (ALTO) servers and Path Computation Elements (PCEs). This document is a product of the Inter-Domain Routing Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
