Wait, why would PEI send to both PE2 and PE3? Sounds odd.

PEI acts as a non-DF for VPLS 10, so no flooding.

I'm leaning towards option B, but I wonder if there's a specific reason PE3 wouldn't get the packet. It feels like it could be a trick question.

I feel like PEI has to send the packet to both PE2 and PE3, but I can't recall which label goes where.

I remember a similar question where PEI had to decide whether to send packets to multiple PEs. I think it was about avoiding loops or something.

I think PEI might not flood the packet since it's a non-designated forwarder, but I'm not completely sure.

I've got a good strategy for this. I'll eliminate the options that don't make sense based on the information provided, then choose the one that best fits the scenario described in the question.

Okay, let me think this through. PEI is the non-designated forwarder for VPLS 10, so that rules out option A. The question is asking what PEI does with the packet, so I need to focus on the remaining options.

Hmm, I'm a bit unsure about this one. The details around PEI's actions after receiving the BUM packet are a bit confusing to me. I'll need to re-read the question carefully.
