Anees,

 

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

 

Any comments

 

Regards

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.

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?
