       |  |    _______________|      |
       |  |_ |  __________ _____    |      AREA401(NSSA)
       |      |                            |    |

|                |==========|                 |
-----------------                     ------------------

I setting zebra095a(1) NSSA-ABR for default-originate in ospfd
but, NSSA Area not injection default-route

AND setting zebra095a(1) for default-originate alway in ospfd
so,default-route injection AREA0 and AREA401

How can I announce default-route only to NSSA?
