Yes you're right Abdul,
But In Edman case, It is not an ABR Backbone router with NSSA ASBR. It's on
different router

I think there is a need to Exercise some caution here in this quote
"cause a non abr backbone router cannot generate a default route". A
non ABR Backbone Router which is at the same time an NSSA ASBR can
indeed generate a default route in fact with the same Area x nssa
default- information-originate command. This is readily applicable
where the NSSA ASBR is not an ABR but is connected to another AS
entirely.
