One-to-Two and Two-to-Two VLAN Mapping Configuration Example
Network requirements
As shown in Figure 21-9 , two VPN A users, Site 1 and Site 2, are in VLAN 10 and VLAN 30
respectively. SP 1 assigns VLAN 100 for VPN A, and SP 2 assigns VLAN 200 for VPN A.
Configure one-to-two and two-to-two VLAN mappings to enable the two sites to communicate across
networks SP 1 and SP 2.

Configuration procedure
1) Configuring PE 1
# Configure an uplink policy test to add outer VLAN tag 100 to VLAN 10 tagged traffic.

# Set customer-side port Gigabitethernet 2/0/1 as a hybrid port, and assign it to VLAN 100 as an
untagged member, so the port forwards VLAN 100 traffic with the VLAN tag removed. On the port,
enable basic QinQ, and apply uplink policy test to the incoming traffic.
