The WG adoption poll has completed.  There is both quite a bit of support for the document as well as some who have concerns for the necessity of the TTZ mechanisms. Given the support as well as the fact that the draft is experimental track, our reading is that we have sufficient basis for experimentation. As discussions of IS-IS area abstraction mechanisms have progressed, it has become apparent that we are not going to reach consensus on a single mechanism. It is our feeling that having multiple mechanisms adopted by the WG on the experimental track is preferable to WG paralysis.

Please republish the draft as draft-ietf-lsr-isis-ttz-00.txt with experimental status.

Subject: [Lsr] LSR WG Adoption Poll for "IS-IS Topology-Transparent Zone" - draft-chen-isis-ttz-11.txt

Based on the discussions in the last meeting and on the mailing list regarding draft-chen-isis-ttz-11, the chairs feel that there are enough differences with draft-ietf-lsr-isis-area-proxy-03 and in the community to consider advancing it independently on the experimental track.

These differences include abstraction at arbitrary boundaries and IS-IS extensions for smooth transition to/from zone abstraction.

We are now starting an LSR WG adoption call for draft-chen-isis-ttz-11.txt. Please indicate your support or objection to adoption prior to Tuesday, September 2nd, 2020.

Thanks,
Acee and Chris
