Technical Summary

   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.

Document Quality

   The document is of high quality.  Since this is a -bis document, 
   the original content had been through the RFC process and started 
   in good shape.  The new text and clarifications introduced in each 
   revision were well-considered and cleanly worded.

   BGP-LS is widely deployed.  The (short) implementation report for this
