Fred,

I agree that LLAs have this restriction, but they are not globally unique.
However, if I understand your draft correctly, MANET's local addresses are
globally unique. Even though a MANET Router might be connected to multiple
MANET networks, the addresses used on the two networks will not be
duplicated and are, in fact, globally unique, making the need for a
Zone/Interface Identifier superfluous. This is how ULA works and why
they are part of the global scope, even though they are not globally
reachable. I think you will want MANET addresses to act and be used more
like ULA rather than LLA, as they are also globally unique and not globally
reachable. Unless I am misunderstanding your intent.
Thanks.
