It's hard to tell as you haven't said where the ASBR are. (remember if
you added a loopback address using the "redistribute static" then that
is also an ASBR. I think for the first part area 1 nssa
default-information-originate would solve that.
Unless I've missed something can you not just configure area 3,4 stub
no-summary to inject a default-route?
Default-information originate in area0?

Subject: area nssa default-route
Here's a scenario wherein
routers 3,4,5 are in area 1 and routers 1,2,6,sw1,sw2 are in area 0 and
sw3
and sw4 are in area 3 and 4
area 1 shud not see external routes from another ASBR's except R4 of
ospf
and i shud allow LSA-3 in area 1.Also i shud annaounce default route in
area
1 and in all other areas. static routes are not allowed.
i cud figure the first part which is i make area 1 nssa and this allows
LSA-3 in provided i dont do a no-summary,Now if i habve to announce a
default route in area 1 and other areas ,shud i be doing
default-information
orginate always? or shud i do area 1 nssa default-originate
thks
