Hmm, I'm not sure. Is it C? Pushing a new label seems like something an eLER would do. Or maybe I'm just hungry and thinking about pushing buttons on a vending machine.

B looks good. The eLER swaps the MPLS label and sends it on. That's what I've learned in my MPLS classes.

I agree, B is the right answer. The eLER's role is to swap the label.

I think the answer is D. The eLER pops the MPLS label and forwards the packet to the next IP router, right? Seems straightforward to me.
