C) EXP? Isn't that where you store the number of eggs you've had for breakfast? Oh wait, that's the 'exp' field, my bad.

Hmm, I'm torn between A) Label ID and C) EXP. Guess I'll just flip a coin and hope for the best.

Maybe you can try flipping a coin to decide between A) Label ID and C) EXP.

That makes sense, Label ID would indeed be a crucial identification field for distinguishing labels in MPLS label switching.

I disagree, I believe it is Label ID because it uniquely identifies the label for forwarding purposes.

I think the identification field used as a PTN to distinguish the label at the bottom of the stack is EXP.

B) BS? Really? What does that even stand for? Definitely going with A) Label ID on this one.

D) TTL seems like the obvious choice here. I mean, that's where you'd expect to find the time-to-live information, not the PTN identifier.

D) TTL is actually used for time-to-live information, not for PTN identification.

I'm pretty sure the answer is C) EXP. That's where the PTN distinguishes the label at the bottom of the stack, right?

That's right, the EXP field in the MPLS label is used by the PTN to identify the label at the bottom of the stack.

Yes, you are correct. The EXP field is used by the PTN to distinguish the label at the bottom of the stack.
