Jari:

Hi!

Yes, we’ll clarify.  We’ll bounce the text by you/Orit before committing to it.

Thanks!

Alvaro.

----------------------------------------------------------------------

Thank you for working on this important spec.

I would like to recommend its approval, but before that I had a request
for a clarification, inspired by Orit Levin's Gen-ART review.

In Section 5.1, what specifically is the requirement regarding OSPF
TTZ/TTZID uniqueness. It just says "unique within a network". For
instance, if I have TTZID 17 under Area 0 and Area 223 among the same set
of routers implementing multiple Areas simultaneously, is that allowed?
Or are different Areas automatically different networks?

Can you specify an algorithm or rule, or make the current wording more
precise?
