Seems like a straightforward process, but I have my doubts.

I think ASBR1 should be pushing the label, right?

Wait, are we sure about ASBR2 forwarding an unlabeled packet?

I definitely remember that PE1 pops a label before forwarding, so option D seems like a solid choice based on what we practiced.

I’m a bit confused about the label operations. I feel like option C could be right, but I can't recall if ASBR1 really pushes a label or not.

I remember a practice question where ASBRs were involved, and I think they usually handle unlabeled packets. So maybe option B is correct?

I think option A sounds familiar, but I'm not entirely sure if PE2 actually pushes a label before sending it to ASBR2.

I'm pretty confident I know the answer to this one. The VPRN model and label switching behavior is something I've reviewed extensively, so I should be able to identify the correct option.

Okay, I think I've got this. The key is to follow the packet flow from CE2 to the destination. Let me walk through each option and see which one matches the correct path.

Hmm, I'm a bit confused by the diagram and the different routers involved. I'll need to review my notes on Inter-AS VPRN models to figure this out.

I'm not sure, but I think C) ASBR1 pushes one label on the IP packet and label-switches it to PE1 makes sense.

I think I'll just go with the flow and see where it takes me. Maybe I'll get lucky and the answer will be 'all of the above'!

Option A seems logical, but I'm worried about the 'one label' part. Shouldn't there be more labels involved?

Agustin

Yeah, the diagram shows only one label being pushed, so option A makes sense.

I agree, one label should be enough for the IP packet to be label-switched to ASBR2.

So, the correct answer must be option B then. ASBR2 forwards an unlabeled IP packet to ASBR1.
