This constraint does not imply that the originator of a Request has to
maintain in its FIB a route that covers precisely the same set of
destinations as the target, priot to issuing the Request.
For example, the originator of a Request may have in its FIB a route
to 192.9.200/24, but may generate NHRP Request for 192.9.9.200.9
as the target.
