SUMMARY

   Current signalling used by MPLS TE doesn't provide support for
   unnumbered links.  These documents define procedures and extensions
   to RSVP-TE and CR-LDP, one of the MPLS TE signalling protocols, that
   are needed in order to support unnumbered links.


RELATED DOCUMENTS

  none


WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK

  Belongs in MPLS.  This ID describes how to assign numbers to
  unnumbered links (sounds like a contradiction) and how to refer
  to these links when defining Explicit Routes, basically mechanisms
  for RSVP-TE and CR-LDP.


WHY IS IT TARGETED AT THIS WG

  This ID extends the mechanisms and procedures of RSVP-TE and CR-LDP
  and hence belongs in MPLS.


JUSTIFICATION

  The primary motivation for this work is the use of unnumbered links.
  This is useful for packet-switched networks, as well as for
  optical networks, where the number of links (fibers, lambdas in a
  fiber, ...) is very large, making IP numbering a daunting task.

  There was a fair amount of discussion in the MPLS WG over this draft.
  The consensus was that this ID addressed a real requirement, and
  there was wide support to make it a MPLS WG document (which it is).
  Some issues that were raised have been addressed; this draft appears
  ready for WG Last Call.
