Dear all,
I have quickly checked and reviewed the document and think it is well written and quite completely describes the requirements and exemplary OAM messages for SFC. My only comment would be for sect. 6.3.1.:

Length is a two-octets-long field, and the value equals the length of the Value field in octets. => Length is a two-octets-long field, and the value equals the length of the data following the Length field counted in octets. 
[As in sect. 6.6.3 as there is no 'Value field' defined for Source TLV!]

Also, I wonder whether in sect. 6.4.1. one should add a Figure describing the format of the 'sub-TLVs' - similar as to Fig. 10 for 'SF Information Sub-TLV' ?

Thanks!
Best regards
Dir[k

Subject: [sfc] Regarding last call for draft-ietf-sfc-multi-layer-oam

I have received a polite request with explanation for delay asking for more time to read and review the subject document.  Given the state of the working group, i want to encourage any and all review.  So I am extending the last call by two additional weeks.

Please read and review the document.
Also, if you are willing to serve as shepherd for this, please let the chairs know.  (Don't worry if you have not shepherded a document before. 
  The chairs are more than happy to help you with the process.)

Thank you,
Joel
