200? No way, that sounds too much!

I’m leaning towards 150. Seems right.

I feel like the answer could be 150, but I can't recall the exact reasoning behind it. I hope I remember the right formula!

I’m a bit confused about how the loopback interface affects the cost. Did we cover that in detail?

This question seems similar to one we practiced where we had to calculate the total cost through multiple routers. I think the cost might be 100.

I remember we discussed OSPF cost calculations in class, but I'm not entirely sure how to apply it here.

Okay, I think I've got it. The LoopbackD interface is on R2, and it's being advertised into area 1. So the path from R1 to 10.2/32 would be R1 -> R2 (cost 50) -> LoopbackD (cost 50), for a total cost of 100. I'm confident that's the right answer.

Hmm, I'm not totally sure about this one. The wording is a bit tricky, and I'm not 100% clear on how OSPF cost calculations work in this type of scenario. I'll need to think it through carefully and maybe even sketch out the network topology to visualize the path.

This looks like a straightforward OSPF routing question. The key is to follow the path from R1 to the 10.2/32 network and add up the link costs. Based on the information provided in the figure, I think the answer is 100.

I'm a bit confused by the wording of the question. Is the LoopbackD interface on R1 or R2? And what does it mean that the interface is "advertised in area 1"? I'll need to re-read the question carefully to make sure I understand the setup.

Okay, let's think this through step-by-step. The question is asking about the cost of R1 reaching the 10.2/32 network, which is advertised in area 1. The figure shows the cost values of the links, so I need to add up the costs along the path from R1 to the 10.2/32 network.

Hmm, this looks like a trick question. The cost should be 100, but I bet the exam writers will try to trip us up with the 'advertised in area 1' part. Better double-check my work.

Wait, isn't the answer 50? The question states that the LoopbackD interface is advertised in area 1, so the cost should be the same as the interface cost.

The cost of R1 reaching 10.2/32 should be 100, since the cost of the LoopbackD interface is 50 and the link cost is also 50.
