As John Z pointed out, the company has a lot of control over how this
is done.  With coordination between xTRs (in the case of ALT), the
Map-Request can go to a "near" one and the Map-Reply can carry a
specific answer.  Or not.  Complexity can be pushed outside, or be
placed in the company's edge (control only), or brought all the way in
to internal routing.  You choose your trade-off points.
