[c-nsp] OSPF NSSA question

[Ruben Alvarez]

Thanks.  that's sounds like what I want, but it says:

 

"Configure this command on NSSA ABRs only. After you define the NSSA totally
stub area, Area 1 has these characteristics in addition to the NSSA
characteristics:

 

      -No type 3 or 4 summary LSAs are allowed in Area 1. This means no
inter-area routes are allowed in Area 1.

 

      -A default route is injected into the NSSA totally stub area as a type
3 summary LSA."

 

So no IA routes are allowed in area 1.  But I have N2 routes?

Hello,

I have a question.  I have recently setup a second OSPF area.  The ABR has
three routers connected to it (area 1) in a hub and spoke configuration.
The routers get a default route to the ABR via default information
originate.  Now the ABR has all the N2 routes for the three routers.  But so
do all three routers, which isn't needed.  They only have one interface and
a default route.  Is there a way I can ignore all routes in the area except
the default route coming from the ABR?
