[j-nsp] How to prevent black-hole in NSSA

[Michael]

Hi, guys 

could you pls explain How to prevent black-hole in NSSA.

Let say there are four  routers in area 10 which is NSSA, two ABR
connected to the backbone. one router redistribute external route
to the NSSA area.

as i know we should do something in two ABR JUNIPER router, in order to
prevent blackhole.

from other area, to trace the external route, we would find that the
route is not gone through the shortest path, it means have blackhole in
the NSSA area.
