Hello All,

We would like to share an update of the draft:
https://datatracker.ietf.org/doc/html/draft-ietf-idr-bgp-ls-sr-policy-04

Summary of changes is as follows:

1) Clarification of the invalidation drop in the SR CP State TLV
(consistent with what was done for the BGP SR Policy SAFI draft recently)
2) Editorial updates for references to drafts that became RFCs
3) Updated affiliations
4) Updated references to specific sections of RFC9256 for individual SR
Policy and CP identifiers
5) Updated IANA section due to overlap with PCEP SR Policy CP draft that is
progressing in parallel

More importantly, there is now an implementation report that has been
updated at
https://wiki.ietf.org/group/idr/implementations/draft-ietf-idr-te-lsp-distribution
(pardon the old name still on the link - I couldn't fix it)

Request WG members to please report/update any implementations that you may
be aware of. If you need any help, please reach out to the authors
(Ketan/Jie) or our IDR chair/shepherd (Sue).

Thanks,
Ketan (on behalf of co-authors)
