Hi Robert,
The "transition" means transfer/abstract a zone to a single virtual node
smoothly and roll the virtual node back to the zone smoothly.
TTZ draft contains a solution for the "transition", which reduces the
traffic interruption when a zone is abstracted to a node and vice

[HC]: There are three LSR drafts that experiment/explore the new ways for
scalability.

[HC]: TTZ provides users flexibility to define a zone and abstract the zone to
a single node for

Hmmm maybe I missed some explanations by authors, but to me concept of
zones is positioned as an addition to the concept of areas or levels - not
a replacement of those.
So when you say "transition" means that something existing no longer would
be in place after

Title : Area Proxy for IS-IS

Since careful planning and design is required to split a L1 Area into L1a
L1b using TTZ as this is a major effort to plan out. It maybe easier as
part of the planning effort to just create two separate L1 areas that have
different L1/L2 attachment points for the attach bit to be propagated. Use

Great so we see the problem description. This is progress !
Allow me to observe two points:
* IGP scalability can be easily solved with the additional levels of
current abstraction instead of introducing new types of abstraction into
it. Ref:

Oh then I perhaps completely missed the value and power of TTZ.
It seems that in TTZ instead of careful planning of your abstractions the
plan is to randomly create zones and see what happens - is this
