I ran it in the lab. Both answers c and d gave the same results. So they do
both work.

Subject: Re: Two areas don't make an ABR?
After reading the explanation, I still think that both answers C and D would
work. The explanation assumes that assigning Loopback0 to area 0.0.0.0
would not suffice to make it an ABR. From what I've heard, this actually
would suffice but perhaps I'm misunderstanding something.
We had this discussion on the other list a couple of months ago. We were
discussing what would happen in a hub and spoke environment where there were
no links on the hub router in area 0.0.0.0. It was decided that as long as
there was some interface on the hub router that was in area 0.0.0.0, this
would satisfy the requirements. Perhaps that would only apply to interfaces
that actually pass traffic and not to the loopback interface.
Hmm...additional lab research is required, I think.

John

| Which OSPF configuration fragment will cause abr1 to function as an
| area border router?
|
| hostname abr1
| int loop0
| ip addr 10.0.0.1 255.255.255.248
| int e0
| ip addr 192.168.0.1 255.255.255.0
| int e1
| ip addr 192.168.1.1 255.255.255.0
