Dear IS-IS working group,

have posted a new version of the IS-IS label advertisement draft.
the major changes between -00 to -02 are:

-support for signaling Bypass (FRR) Labels
-support for SPT labels using RFC4761 'VPLS' style label block
 advertisements. this is mainly to comply to RFC3031 which
 mandates that label allocation is a strict local procedure,
 and still not loose the comfort of getting an
 automatically provided transport mesh (similar to LDP).

 This provides similar functionality like first mentioned in
 http://tools.ietf.org/id/draft-tian-mpls-lsp-source-route-01.txt
 *without* the need of an RFC 3031 architectural violation.

 The advertised label blocks allow in addition to specify a particular
 rfc5120 topology and an algorithm (SPT). we got feedback
 that having a pluggable algorithm (e.g., but not limited to: MRT)
 would solve a couple of practical use cases for
 'infrastructure LSPs' in the area of make-before break, ordered FIB,
 etc.

the authors are looking for feedback and suggested text changes
to improve the draft. - please help us to make it better ;-)

as a vehicle to foster open collaboration we are VCing our work in github.
feel free to clone the repository at:

send us pull requests with your suggested changes (or diffs using email);

thanks,

> Abstract:
>   Historically MPLS label distribution was driven by protocols like
>   LDP, RSVP and LBGP.  All of those protocols are session oriented.  In
>   order to obtain a label binding for a given destination FEC from a
>   given router one needs first to establish an LDP/RSVP/LBGP session
>   with that router.
> 
>   Advertising MPLS labels in IGPs advertisement
>   [I-D.gredler-rtgwg-igp-label-advertisement] describes several use
>   cases where utilizing the flooding machinery of link-state protocols
>   for MPLS label distribution allows to obtain the binding without
>   requiring to establish an LDP/RSVP/LBGP session with that router.
> 
>   This document describes the protocol extension to distribute MPLS
>   label bindings using the IS-IS protocol.
