7)  When the promiscuous port Port5 receives the response packet, it tags this packet a 
default VLAN ID 5 and learns the MAC address entry mac_a+VLAN5+Port5. 
8)  According to the MAC address duplication, this MAC address entry is copied to VLAN 
2 and VLAN 3, and the switch adds two more MAC address entries 
mac_a+VLAN2+Port5 and mac_a+VLAN3+Port5 to its address table. 
9)  The switch looks up the MAC address table based on mac_2+VLAN5. It finds out the 
egress port Port2 through which the packet is forwarded to PC2 untagged. 
After all the steps above are finished, the bidirectional communication between PC2 and the 
Router is achieved.
