Totally agree, D seems like the false one here!

Wait, does PE2 really pop all labels? That seems off.
TR

Sounds about right, but I'm not sure about ASBR2's role.

I think ASBR1 just pops the LDP label, right?

PE1 definitely pushes three labels, that's standard.

I’m pretty sure PE2 does pop all the labels, but I wonder if it really forwards the unlabeled packet directly to the destination. That seems a bit off.

I feel like ASBR2 should be swapping the BGP label, but I'm not confident about whether it pushes an LDP transport label afterward.
ME

I think option B sounds familiar from a practice question, but I can't recall if ASBR1 actually pops the LDP label before swapping the BGP label.

I remember studying the label stacking process, but I'm not entirely sure if PE1 really pushes three labels. That seems like a lot.

This looks like a tricky one, but I'm going to carefully analyze each option and think through the label operations step-by-step to determine which one is false.

I'm a bit confused by the different label types mentioned. I'll need to double-check my understanding of BGP, LDP, and VPN labels and how they're used in an Inter-AS VPRN.
ME

Okay, I think I've got this. The key is to identify which of the label operations described is not accurate for this scenario.
HO
Hoa

Hmm, the labels mentioned in the options seem to be the key here. I'll need to review my notes on MPLS label stacking and how it's used in Inter-AS VPRNs.

This question looks pretty straightforward, but I want to make sure I understand the details of the Inter-AS VPRN model before answering.
EL

Hmm, I see your point. Maybe I need to reconsider my answer.
QU

I agree with Ellen, A seems like the correct option based on the Inter-AS model.
EL

But A makes sense because PE1 pushes three labels for VPN, BGP, and LDP.

Is it just me, or does this whole Inter-AS VPRN thing sound like a secret government agency? I wonder if they have cool code names too.

This question is making my head spin. I bet the real answer is 'all of the above' and the exam writers are just trying to confuse us.
ME

I think you're all wrong. The correct answer is D) PE2 pops all labels and forwards the unlabeled packet to its destination.
TH
Theola

I'm not sure, but I think it might be C) ASBR2 swaps the BGP label and pushes an LDP transport label.
RA
Raul

No, I believe it's B) ASBR1 pops the LDP label, swaps the BGP label and forwards the IP packet to ASBR2.
PO

I think the answer is A) PE1 pushes three labels on the IP packet: a VPN label, a BGP label, and an LDP transport label.
GE

Wait, is this a trick question? I feel like the answer is hidden in the image or something. Gotta keep my eyes peeled!

User 2: No, I believe it's B) ASBR1 pops the LDP label, swaps the BGP label and forwards the IP packet to ASBR2.

Hmm, I'm a bit unsure about this one. The labels and swapping seem a bit complex for my taste.
EL
Elouise

I disagree, I believe it's C.
EL
Ellen

I think the answer is A.
JO
Josue

Hold up, I think D is the false statement here. PE2 should pop all the labels, not forward the unlabeled packet.
DA
Dacia

User2: Yeah, that doesn't sound right. PE2 should pop all labels.
TW

User1: I agree, PE2 should not forward the unlabeled packet.
MI
Mignon

I'm pretty sure the correct answer is A. The PE1 router should push three labels on the IP packet.
