And also, if you have NOT issued the command clear frame inarp (12.1 and
above) or clear frame-inarp (12.0 and below), the map statements will remain
until you reload the routers.  That will need to be done on router B and
router C.  Routers B and C do not form adjacencies with each other in this
topology *unless* you make use of the full mesh, which you've been
instructed *not* to do.  They both form adjacencies with Router A.  That's
why you add a map statement to each Router B and Router C to point them to
each other via their respective DLCI's to Router A, unless you're explicitly
told not to do that.  (Which is whole different can of worms)

My strategy is shut off inverse arp, clear frame inarp, get the map
statements into the config, write the config, and reload.

You may wish to reschedule your Feb lab date if you're at this point with
OSPF and frame relay a month or so away from your lab.  It only gets more
complex than this, and this concept, while not elementary, is 'core' to your
success in the lab exam.
