Totally agree, R1 is the source for that route!

Wait, R4 gets the default route too? That’s unexpected!

I think only R1 and R2 get it.

R2 and R3 should also have it, right?

I’m pretty confident that R1 and R4 will have the default route, but I’m uncertain about R3. Did we cover that in class?

I feel like R2 should have the default route too, but I can't recall if it depends on the level of the IS-IS area.

I remember practicing a similar question where R1 advertised a default route, and I think R4 might also receive it.

I think R1 definitely has the default route since it's the one importing it, but I'm not sure about R2 and R3.

I'm a bit confused by the topology here. How does the default route get propagated between the level-1 and level-2 areas? I'll need to review the IS-IS route redistribution rules to make sure I understand this correctly.

This seems straightforward. R1 is advertising the default route, so R2 and R3 should receive it since they are in the same level-1 area. R4 is in a different level-1 area, so it shouldn't have the default route. I'm pretty confident in this answer.

Okay, let me think this through step-by-step. R1 is importing the default route using the command, so it should have the default route. But the question is asking which other routers will have it. I'll need to consider how IS-IS propagates routes between levels.

Hmm, this looks like it's testing our understanding of how the default-route-advertise command works in IS-IS. I'll need to carefully review the topology and the command details to determine which routers will have the default route.

This seems like a pretty straightforward question. The key is to identify the phase that wasn't adequately covered in the description.

I remember we practiced a similar question on planned order releases, but I'm a bit unsure about the specific weeks here.

This is like a game of hide-and-seek, but with routers instead of people. I wonder if the correct answer is 'all of the above'?

Okay, let's see. If R1 is advertising the default route, then all the other routers should be able to see it, right? I'll go with option D, R1.

Yes, R1 is the correct choice because it is the router importing and advertising the default route.

I agree, R1 should have the default route in its routing table since it is the one importing it.

Hmm, let me think about this. Since R1 is the one importing the default route, I'd guess it's also the one that has it in its table. But I could be wrong.
