Dear OSPF working group, have posted a new version of the OSPF 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 rfc4195 topology-ID and an algorithm (e.g. 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: https://github.com/hannesgredler/draft-gredler-ospf-label-advertisement.git send us pull requests with your suggested changes (or diffs using email); thanks, /hannes Begin forwarded message: > From: <[email protected]> > Subject: New Version Notification for > draft-gredler-ospf-label-advertisement-02.txt > Date: May 6, 2013 6:34:55 PM GMT+02:00 > To: Tom Scholl <[email protected]>, Hannes Gredler <[email protected]>, > Shane Amante <[email protected]>, Luay Jalil <[email protected]> > > > A new version of I-D, draft-gredler-ospf-label-advertisement-02.txt > has been successfully submitted by Hannes Gredler and posted to the > IETF repository. > > Filename: draft-gredler-ospf-label-advertisement > Revision: 02 > Title: Advertising MPLS labels in OSPF > Creation date: 2013-05-06 > Group: Individual Submission > Number of pages: 27 > URL: > http://www.ietf.org/internet-drafts/draft-gredler-ospf-label-advertisement-02.txt > Status: > http://datatracker.ietf.org/doc/draft-gredler-ospf-label-advertisement > Htmlized: > http://tools.ietf.org/html/draft-gredler-ospf-label-advertisement-02 > Diff: > http://www.ietf.org/rfcdiff?url2=draft-gredler-ospf-label-advertisement-02 > > Abstract: > Historically MPLS label distribution was driven by protocols like > LDP, RSVP and LBGP.
