Wait, MPLS has backup dancers? I thought it was more like a one-man show, just labeling everything in sight!

I guess MPLS data traffic has some backup plans after all!

C) MPLS data traffic will not be discarded because router R1 received labels from both next-hops, routers R2 and R3.

A) MPLS data traffic will be discarded until the IGP finds a new next-hop to router R3.

C is the answer, no doubt. It's like having a backup dancer in case your main one trips on stage. MPLS is the diva, and the labels are the backup dancers!

Exactly, it ensures that the traffic keeps flowing smoothly even if there are disruptions.

It's like a safety net in case something goes wrong with the primary path.

Hmm, I'm still a bit confused. Is there a way to test this in a lab environment? I'd love to see it in action.

Aha! I think C is the correct answer. If R1 received labels from both next-hops, it can continue forwarding traffic even if the link between R2 and R4 goes down.

I think D is the correct answer. Fast reroute capability on R2 should ensure that the MPLS data traffic is not discarded.

But what if the link between R2 and R4 goes down? Will the traffic still be forwarded to R6?

I agree, C seems like the correct answer. R1 having labels from both next-hops should help in forwarding traffic.

The answer seems to be C, but I'm not sure why. I need to understand how MPLS label distribution works in this scenario.

That makes sense. So even if one link goes down, the traffic can still reach its destination through the other path.
