Just like an area border: everything.

To your point before about connectivity inside, why wouldn't you advertise
everything?

I don't understand what you mean by 'statically configuring'.

The internal nodes are routers just like any other..yes, they would know
(as written in the draft) that they are internal to the TTZ..just like a
