NEW QUESTION 50
Which of the following statements about the VPLS packet forwarding are true?

If a PE receives broadcast packets from a local user, the PE forwards the packets to all other interfaces
In the same VSI and all other PEs.

If the destination MAC address of a packet is not a broadcast address and a PE has not learned the MAC
address, the broadcast this packet in one VSI

If the destination MAC address of a packets is not a broadcast address and a PE has not learned the
MAC address, the PE broadcast this packet in on VSI.

If a receive broadcast packet sent a remote PE, it forwards the packet only to the AC interface instead of
other PEs.
