Based upon the exhibit,

which of the following statements about the forwarding of BUM traffic is FALSE?

DPE2 decapsulates the packets received from PE3 and forwards the frames to CE2.

CPEI forwards the traffic received from PE3 to CEI, and CEI discards it based upon the ESI label.

BPE3 adds an ESI label to packets forwarded to PEI because PEI is connected to the same Ethernet segment.

APE3 replicates the traffic and sends it to all PES in its VPLS I flooding list.

Show Suggested Answer

Suggested Answer: B

PE3 does not add an ESI label to packets forwarded to PE1 because PE1 is connected to the same Ethernet segment.PE3 adds an ESI label only to packets forwarded to PEs that are not connected to the same Ethernet segment, such as PE21.

This question seems similar to one we practiced about multicast forwarding. I think it might be related to how switches handle BUM traffic.

I remember we discussed BUM traffic in class, but I’m not entirely sure which statement might be false.

I think I see what they're getting at. Let me double-check my understanding of BUM traffic forwarding and see if I can spot the inaccurate statement.

I'm a bit lost on this one. The exhibit doesn't seem to give me enough information to confidently identify the false statement. Might need to guess on this one.

Okay, I've got a strategy - I'll go through each statement and check it against the information in the exhibit. Gotta be methodical here.

The exhibit shows some network topology, but I'm not sure how to use that to determine which statement is false. Might need to review my notes on BUM traffic forwarding.

Hmm, this looks like a tricky one. I'll need to carefully analyze the exhibit and think through the different forwarding options.
