Hello Ole and all,

I re-read this version again with the following comments for the WGLC.

1. Section 4.2.2.2, the penultimate bullet.
The sentence "The traceroute process at node N4 checks if its local SID (B:2:C31) is locally programmed" should be "The traceroute process at node N4 checks if its local SID (B:4:C52) is locally programmed".

2. Requirements Language
[RFC8174] should be added as a nomative reference.

3. Section 3.5 SRH TLV
This section only tells us SRH TLV is defined in ietf-6man-segment-routing-header, nothing else. I think this section should be removed.

4. Section 4.3 Monitoring of SRv6 Paths
This section is a story or a use case. No specification is defined in this section. It should be removed or moved to an appendix.

5. Section 2.1 Abbreviations
ICMPv6 is defined in RFC4443. Why does this draft use it as multi-part ICMPv6 defined in RFC4884. This is confusing.

6. Section 4.1.3 Error Reporting
ICMPv6 is defined in ICMPv6 related RFCs. Does this section want to extend ICMPv6? If yes, I don't think this doc is the appropriate place. If no, why do we need this section? to emphasize the things that a router should do?

With all the commets above, I don't think this doc is mature enough to pass the WGLC.

Best Regards,
Zhenqiang Li
