Port1/0/1 of PE1 and PE2.
Trunk port
Port1/0/1 and Port1/0/10 of PE1 and PE2.
Configuration procedure is as follows:
PE1、PE2:
switch(Config)#interface ethernet 1/0/1
switch(Config-Ethernet1/0/1)#switchport mode trunk
switch(Config-Ethernet1/0/1)# vlan-translation enable
switch(Config-Ethernet1/0/1)# vlan-translation 20 to 3 in
switch(Config-Ethernet1/0/1)# vlan-translation 3 to 20 out
switch(Config-Ethernet1/0/1)# exit
switch(Config)#interface ethernet 1/0/10
switch(Config-Ethernet1/0/10)#switchport mode trunk
switch(Config-Ethernet1/0/10)#exit
