Definitely discarded, no LFIB entry means no forwarding!

I thought it would be flooded, not discarded.

Wait, are you sure about that?

Totally agree, that's how MPLS works!

Fragmentation seems off for this scenario. I think it’s either flooding or discarding, but I’m leaning towards discarding.

I feel like this is similar to a question we did in class, and the answer was definitely about discarding the frame.

I'm not entirely sure, but I remember something about flooding in a different context. Could that apply here?

I think if the label isn't in the LFIB, the router just discards the frame, right? That seems to be what we practiced.

Okay, let me walk through this step-by-step. If the MPLS router can't find the label in its LFIB, it won't be able to forward the frame properly. So the logical action would be to discard the frame to avoid any issues. I'm feeling good about B as the answer.

Hmm, I'm not totally sure about this. I think the frame might get flooded, but I'm not 100% certain. I'll have to think it through carefully.

I'm pretty confident I know the answer to this one. MPLS routers discard frames with unknown labels to avoid forwarding them incorrectly.

I'm a bit confused on this one. Is there a possibility the frame could get fragmented? I'll have to review my MPLS notes to make sure I understand the proper behavior in this scenario.

The undo feature and the adjustable user interface seem like the best options for error tolerance. I'll choose those.

I practiced a similar question where encryption was linked to protecting data from attackers, so A seems likely to me.

B) The frame will be discarded. Yep, that's the way to go. No need to waste resources on a frame that's got a non-existent label.

A) The frame will be flooded? Haha, that's a good one! Flooding an MPLS network? Next thing you know, they'll be asking us to route frames using carrier pigeons.

A) Yeah, flooding would be a disaster in an MPLS network.

C) The frame will be fragmented? Really? Fragmentation in an MPLS network? I think the exam writer needs to brush up on their MPLS knowledge.

I think the frame will be fragmented to try and match the label.

B) The frame will be discarded. That's the correct answer, right? I mean, who wants to flood the network with a frame that doesn't even have a valid label?

Exactly, discarding the frame helps maintain network efficiency.

Flooded frames can cause unnecessary traffic and fragmentation is not necessary.
RO
Robt

Yes, that's correct. Discarding the frame is the best option in that case.

I believe the frame will be flooded to find the correct path.
