# Configure customer-side port Ten-GigabitEthernet 1/0/2 as a trunk port, and assign the port to
original VLANs and translated VLANs.
[SwitchA] interface ten-gigabitethernet 1/0/2
[SwitchA-Ten-GigabitEthernet1/0/2] port link-type trunk
[SwitchA-Ten-GigabitEthernet1/0/2] port trunk permit vlan 1 2 3 102 202 302
[SwitchA-Ten-GigabitEthernet1/0/2] vlan mapping 1 translated-vlan 102
[SwitchA-Ten-GigabitEthernet1/0/2] vlan mapping 2 translated-vlan 202
[SwitchA-Ten-GigabitEthernet1/0/2] vlan mapping 3 translated-vlan 302
[SwitchA-Ten-GigabitEthernet1/0/2] quit
# Configure network-side port Ten-GigabitEthernet 1/0/3 as a trunk port, and assign the port to
the translated VLANs.
[SwitchA] interface ten-gigabitethernet 1/0/3
[SwitchA-Ten-GigabitEthernet1/0/3] port link-type trunk
[SwitchA-Ten-GigabitEthernet1/0/3] port trunk permit vlan 101 201 301 102 202 302
[SwitchA-Ten-GigabitEthernet1/0/3] quit
2. Configure Switch B in the same way as you configure Switch A.
Verifying the configuration
1. Display VLAN mapping information on Switch A.
[SwitchA] display vlan mapping
Interface Ten-GigabitEthernet1/0/1:
Outer VLAN Inner VLAN Translated Outer VLAN Translated Inner VLAN
1 N/A 101 N/A
2 N/A 201 N/A
3 N/A 301 N/A
Interface Ten-GigabitEthernet1/0/2:
Outer VLAN Inner VLAN Translated Outer VLAN Translated Inner VLAN
1 N/A 102 N/A
2 N/A 202 N/A
3 N/A 302 N/A
2. Display VLAN mapping information on Switch B.
The command output on Switch B is similar to that on Switch A.
The output shows that one-to-one VLAN mapping is successfully configured on Switch A and
Switch B.
One-to-two and two-to-two VLAN mapping configuration
example
Network requirements
As shown in Figure 40, two VPN A branches, Site 1 and Site 2, are in VLAN 5 and VLAN 6, respectively.
The two sites use different VPN access services from different service providers, SP 1 and SP 2. SP 1
assigns VLAN 100 to Site 1 and Site 2, and SP 2 assigns VLAN 200 to Site 1 and Site 2.
Configure one-to-two and two-to-two VLAN mappings to enable the two branches to communicate
across networks SP 1 and SP 2.
