From what I studied, the outer label is typically the one that gets exchanged for a new label during the SWAP operation.

I’m a bit confused about the inner and outer labels. I feel like the inner label gets swapped for a new one, but I can't recall the exact details.

I remember practicing a similar question where we had to identify which label gets swapped. I think it was about the outer label being replaced.

I think the MPLS SWAP operation involves replacing the outer label, but I'm not entirely sure if it's just that or if there's more to it.
