Hi Ali,
   
    One more important point here is,
   
   you can not redistribute static default route in OSPF. (ip route 0.0.0.0 0.0.0.0 )
  And also when you redistribute eigrp or rip which generates default route, it will not redistributed into OSPF.
   
  Please read the Cisco tech support documents
  http://www.cisco.com/en/US/tech/tk365/tech_configuration_examples_list.html#anchor6
   
  Thanks,
   
  Anees.

I have tried default-information originate always on ASBR but it is not working as well. I have also tried ip route 0.0.0.0/0 and redistribute static even then it is not generating a default route.

  If the ASBR is also the ABR you could do "area xx nssa default-information" but if it is not, then when a router injects a default route its considered to be an ASBR.

  Well the ASBR can also be the ABR, but if it is not, try default-information that will work.

  Anees,

This is exactly what I have experienced in my lab. ASBR is not generating
any default route.

Any comments

Ali

Hi,

I don't think ASBR in NSSA can generate Default route. the only command
applicable in the Intra area routers or ASBR in NSSA are area X nssa.

All the area X nssa <options> are applicable in ABR NSSA router or ABR and
ASBR NSSA router.

This is what I see in the lab practice. Please correct me if I am wrong.

Thanks,

Anees.

HI Ali,
Yes. You can configure ASBR in NSSA to generate default route. You have to
confiure the ABR as "area nssa" and in ASBR configure "area nssa
default-information-originate". By this you will get Inter-area routes from
ABR into this NSSA area and a default router from ASBR.

To suppress N2 within NSSA, you need to configure "area 2 nssa
no-redistribute default-information-originate" in ASBR.

Nagendra

Can ASBR in NSSA generate a default route (if ABR and ASBR are not the same
routers); also can we suppress N2 routes within NSSA maintaining the full
reachability?
