I think there's some misunderstanding.  Nothing has to know about X
endsystems.  Nor did anything have to know about N routers before.

In the shim6 approach, a host only needs to know about its correspondent
hosts.  From a scalability perspective, this is unchanged from
previously, only the constants are bigger.
