Hi, Jim and Joel,

I support advancing draft-ietf-sfc-ioam-nsh.

One comment for consideration：

Suggest to replace the following figure in“3.  IOAM data fields encapsulation in NSH”

Dear WG:

The chairs have extended the WGLC for a further 2 weeks due to the lack of feedback from the WG on the original WGLC.

Please read the document and provide comments to the SFC WG mailing list no later than September 17th 2021. Note that this document is a normative reference for https://datatracker.ietf.org/doc/html/draft-ietf-sfc-proof-of-transit that is currently in AD review and we would therefore like to conclude this WGLC so that its dependent documents can further progress.

Thanks!

Jim & Joel
