    Title: RE: default route into NSSA
    
   Derek,
   
   You got it on the nose. I tried adding *no-summary* and this is what
   I ended up with:
   
   Gateway of last resort is 11.1.0.5 to network 0.0.0.0
   
   D 172.17.0.0/16 [90/2297856] via 172.16.0.7, 00:06:41, Serial0
   C 172.16.0.0/16 is directly connected, Serial0
   D 172.18.0.0/16 [90/2297856] via 172.16.0.7, 00:06:41, Serial0
        11.0.0.0/16 is subnetted, 1 subnets
   C 11.1.0.0 is directly connected, FastEthernet0
   O*IA 0.0.0.0/0 [110/21] via 11.1.0.5, 00:01:38, FastEthernet0
   O 172.16.0.0/12 is a summary, 00:06:33, Null0
   
   BUT, My original question is still out there... R1 was generating a
   default that r3 was picking up. R4 never got the default route
   because it is in a NSSA. Is that by design? Is there something that
   I can do to pass the default into the NSSA, or do I have to add *area
   9 nssa default-information-originate*
   
   Regards,
   Aaron

   I believe that configuring that command on the abr would make the area
   totally stubby which makes it so type 3's are also blocked. No IA
   routes
   other than a default out I think would be present inside the area.
   
   I guess I don't think this would allow a default into the nssa area.
   
   I believe that if the abr in injecting a default into the nssa area
   would be
   fine. I would think that if the backbone knows about the default you
   generated on some router and then once the abr receives the traffic,
   he
   would forward it to his default.
   
   Thoughts?

   You need to add 'no-summary' to the area command you
   have.
