  I can't take it any more.
  Aren't we talking about a totally stubby NSSA here? Or am I just way
  off
  base?

  Not to speak for Brian here, but apparently the task specifically
  referred
  to external routes not being flooded (or entering) into the
  NSSA. The
  first
  thing that comes to my mind is 'area nssa no-redistribution.' I have
  not
  seen the actual scenario so I may be missing a piece of it and could
  be
  wrong.
