Yes, but that doesn't make them the same.

Jules 7 days ago

But aren't they sometimes referred to as service labels?

Della 12 days ago

I agree with Michael.

Michael 18 days ago

Because inner labels are different from VPN labels.

Jules 23 days ago

Why do you say that?

Michael 28 days ago

I think option C is false.

Katheryn 1 month ago

Yeah, B is misleading. P routers just forward.

Stevie 1 month ago

So, B is definitely the odd one out here.

Kristel 1 month ago

A is true. MP-BGP is used for signaling.

Devora 2 months ago

D makes sense. Egress PE needs to know the VPRN.

Willow 2 months ago

C is correct. Inner label is a common term.

Oliva 2 months ago

I’m leaning towards C being false. Inner label? Not sure.

Katheryn 2 months ago

Agreed, B seems off. Labels stay intact.

Stevie 2 months ago

I think B is false. P routers don’t swap labels.

Ruthann 2 months ago

I agree with you, CyberSkeptic, D) doesn't sound right!

Alex 3 months ago

Wait, are we sure about D)? That seems off to me.

Karina 3 months ago

B) sounds right, labels do get swapped at P routers.

Josphine 3 months ago

I think C) is correct too, inner label is a common term.

Roy 3 months ago

A) is true, MP-BGP is used for signaling.

Dannette 3 months ago

I’m leaning towards D being false because I thought VPRN was more about the overall service rather than just indicating to the egress PE.

I’m a bit confused about the role of MP-BGP in signaling. I thought it was crucial for label distribution, so A seems true to me.

Johnetta 4 months ago

I feel like I’ve seen a question similar to this in our practice tests. I think the inner label is definitely referred to as the service label, so C seems true.

Carma 4 months ago

I think option B might be the false one, but I'm not entirely sure. I remember something about labels not being swapped at every router.
