Joel, all, 

(1) 

draft-guichard-sfc-nsh-dc-allocation-07 addressed the comments I had on -06 (https://github.com/boucadair/IETF-Drafts-Reviews/raw/master/draft-guichard-sfc-nsh-dc-allocation-06-rev%20Med.doc). Many thanks to the authors. I'm happy with this document to be adopted.

In order to remove the dependency on draft-penno, the authors may consider adding a pointer to the format of the Opaque Service Class when F=02. For example, the text can indicate that the format is the one depicted in Figure 2 of RFC6759:

    0                   1                   2                   3
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    |Class. Eng. ID |zero-valued upper-bits ... Selector ID         |
    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

                    Figure 2: Selector ID Encoding

The text should also warrant that some defined selector IDs are encoded in 5 bytes. Evidently, those cannot be inserted in this MD-1 format. The text should call those explicitly (See Section 4.2 of RFC6759). 

(2) 

I do also support draft-napper-sfc-nsh-broadband-allocation.

Cheers,
Med
