One-to-two and two-to-two VLAN mapping configuration
example
Network requirements
As shown in Figure 82:
• 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. SP 2 assigns VLAN 200 to Site 1 and Site 2.
Configure one-to-two VLAN mappings and two-to-two VLAN mappings to enable the two branches
to communicate across networks SP 1 and SP 2.

Configuration procedure
1. Configure PE 1:
# Create VLANs 5 and 100.
<PE1> system-view
[PE1] vlan 5
[PE1-vlan5] quit
[PE1] vlan 100
[PE1-vlan100] quit
# Configure a one-to-two VLAN mapping on the customer-side port (Ten-GigabitEthernet 1/0/1)
to add SVLAN tag 100 to packets from VLAN 5.
