the packet entering that port is addressed to unknown MAC addresses. The packet should be flooded to
all other ports in VLAN 5.

This is an example of the output when the packet coming in on port 1 in VLAN 5 is sent to an address
already learned on the VLAN on another port. It should be forwarded from the port on which the address
was learned.
