The below describes the situation where an ASBR happens to be an NSSA ABR
at the same time. In this case, the desire is to bring externals into the
network on that router, yet not leak them into the NSSA area. The
no-redistribution command accomplishes that nicely.
However, I think the original poster was looking more for how to restrict
the Type 7 to Type 5 conversion that the NSSA ABR will perform by
default. In this case, adding a summary address with the not-advertise
option for the prefixes you wish to restrict accomplishes this. The
following link is quite helpful in explaining both of these situations in
some detail.
