The IESG has received a request from the Inter-Domain Routing WG (idr) to
consider the following document: - 'Distribution of Link-State and Traffic
Engineering Information Using
   BGP'
  <draft-ietf-idr-rfc7752bis-11.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2022-11-14. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   In many environments, a component external to a network is called
   upon to perform computations based on the network topology and the
   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 applies to physical and virtual (e.g., tunnel)
   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 obsoletes RFC7752 by completely replacing that
   document.  It makes some small changes and clarifications to the
   previous specification.  This document also obsoletes RFC9029 by
   incorporating the updates that it made to RFC7752.
