| Then you'd be in violation of the scoped addr architecture doc,
| since you're sharing the same global prefix (prefix2) across
| two site zones.
If that's what that doc says, then it needs to change. Trying to make
a strict hierarchy out of the different kinds of addresses is neither
necessary, nor desirable. Many sites will choose to implement it that
way, but it shouldn't have to be required.
If I have just a single point of external connectivity, and hence am
getting just a single global prefix, there's no reason at all that I can't
run multiple sites (in the sense of site local addressing) inside there -
in fact I thought that was one of the original planned scenarios.
Similarly, there's no reason that I can't run multiple global prefixes
within one site.
All the same should apply to subnets.
I can understand if you don't want to (yet) define how to make some of
these situations work, or if some (eg: routing) protocols don't want to
support all of the possibilities. That's fine.
But an addr architecture doc certainly shouldn't be banning any of them.
