Hi WG,

This email begins the WG adoption poll for draft-li-pce-pcep-srv6-yang-07.

https://datatracker.ietf.org/doc/draft-li-pce-pcep-srv6-yang/

Should this draft be adopted by the PCE WG? Please state your reasons - Why / Why not? What needs to be fixed before or after adoption? Are you willing to work on this draft? Review comments should be posted to the list.

<tp2>
Oppose.
It is those expired references.   We have I-D that have been sitting in the RFC Editor queue waiting for their references to catch up for 1108 days - yes, three years - and in one case, the referenced I-D has changed so that the first document is no longer valid and will have to be taken back into the WG to be revised, if anyone is still around who is familiar with it and willing to work on it. 

With hindsight, such I-D should have been held and not forwarded to the IESG, or not adopted in the first place.

Here, I am not familiar with the state of the spring WG and do not know if and when those expired I-D will progress.  A last revision of April 2021 with an I-D that has plenty that needs fixing does not look promising.

Tom Petch

<tp>
The challenge I see is the SR references, one is RFC9256, the others, spring-sr-policy-yang and spring-srv6-yang, are expired; not a good starting point..

The 'when' clauses use absolute form of the path which means that the when is satisfied if there is anything meeting this anywhere in the tree, not just in this path of the tree; if the latter is wanted, then the relative form is required

MSD type could do with a better reference - pce-segment-routing-ipv6 points to RFC8491 but that only sets up an IANA registry which contains many more entries so I think the reference has to be to the IANA registry.

'Add NAI' looks like an unresolved issue

Tom Petch

Please respond by Monday 19th Sept 2022.

Please be more vocal during WG polls!

Thanks!
Dhruv & Julien
