Agree. I also commented this point in the list.

2. Section 4.1.2.2, the last bullet.
Since Flags.O=1 is used in this case, N4 should execute the local SID B:4:C52 after the execution of the pseudo-code specified in section 3.1.1. What is the proper behavior of N4 here?  Generate an ICMP parameter problem message to the Source with Error code "SR Upper-layer Header Error" according to section 4.3.1.2 of draft-ietf-6man-segment-routing-header-22?

Subject: draft-ali-6man-spring-srv6-oam
Zafar,

In draft-ali-6man-spring-srv6-oam, it appears that the SRH O-flag is processed even when Segments Left is equal to zero.

Do you see that as being in conflict with the Section 4.3.1.1 of draft-ietf-6man-segment-routing-header, lines S02 through S04?

                                                                                                                       Ron
