Pierre,
DO you mean the other way around?
0.0.0.0 Is the precise way and not 0.0.0.255
I just want to be sure.

Hi ,
1) I would be as precise as possible and use the 0.0.0.255
In some cases you need the forwarding address to be in the lsa and it
does
not work when using 0.0.0.0
2) the first example nssa, you MUST specify a default. The ABR won't
generate one by itself. The logic I have is that
the default-route maybe coming from the other routing protocol
(injected
in the nssa) or from OSPF itself. Since OSPF can't
know, it requires you to specify
in the second example totally stubby , the only way you would be
able
to get to other OSPF areas is by a default , so OSPF automatically
create
the default for you. No choice there
It all depends what the lab requirements are....
Hope this is clear,
Pierre
