Dear David and Rao, Thank you for sharing your MPLS-ICI specification during straw-ballot. As you will be aware, many of the contributors to your document also participate in the CCAMP working group, so the level of comments is understandably low. We do have the following observations for your consideration. 1. References. In your liaison to us dated 31st August 2007 you said: "In our specifications we are limited to referring only to documents that have been progressed to the RFC editor queue and beyond." Yet in this document you refer to several Internet-Drafts that have not reached this stage. It may be hoped that these drafts will progress before your final ballot, but nevertheless you should be aware of their current status. The following list of references falls into this category with current status noted for those drafts originating in the CCAMP working group. - draft-ietf-ccamp-inter-domain-rsvp-te Completed updates after IESG review. Planned to move to RFC Editor Queue imminently. - draft-ietf-ccamp-inter-domain-pd-path-comp Completed IESG review. Some editorial changes needed before progression to RFC Editor Queue. Work scheduled during October. - draft-ietf-bfd-base - draft-ietf-bfd-v4v6-1hop - draft-ietf-mpls-bfd (you probably mean draft-ietf-bfd-mpls) - draft-ietf-idr-route-filter - draft-ietf-pwe3-ms-pw-requirements - draft-ietf-pwe3-pw-mib - draft-ietf-pwe3-pw-mpls-mib - draft-ietf-bfd-mib 2. Bidirectional Function at the ICI In the CNI spec you liaised to us before used GMPLS protocols, in particular to be able to support bidirectional services. Looking at the ICI specification it is unclear whether you intend to have this level of support. Looking at Annex D there is no reference to any protocol specification, although there is a reference to the CNI. Further the references table in section 5 does not reference RFC3473. Lastly, if it is your intention to support GMPLS signaling, you may also need to reference the GMPLS signaling MIB modules. 3. Broken Reference In D.2.3 you reference RFC3471 for RSVP-TE Graceful Restart. This is not the reference you intend. It is unclear whether you mean RFC3209, RFC3473, or draft-ietf-ccamp-rsvp-restart-ext, or possibly all of these. Best regards, Adrian Farrel and Deborah Brungard IETF CCAMP Working Group Co-Chairs
