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

[Acee Lindem (acee)]

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.

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

Abstract:
   This document presents a topology-transparent zone in an area.  A
   zone is a block/piece of an area, which comprises a group of routers
   and a number of circuits connecting them.  It is abstracted as a
   virtual entity such as a single virtual node or zone edges mesh.  Any
   router outside of the zone is not aware of the zone.  The information
   about the circuits and routers inside the zone is not distributed to
   any router outside of the zone.
