NAME OF I-D:
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.
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.
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.
