Hi Shwetha, thank you for the proposed resolution. I agree with Med, direct normative reference to I-D.ietf-sfc-oam-packet seems like the logical conclusion of our discussion of the use of the NSH O bit. Please note that we're referring to I-D.ietf-sfc-oam-packet in the Active SFC OAM draft, e.g.,: The O bit in NSH MUST be set, according to [I-D.ietf-sfc-oam-packet].
