One-to-two and two-to-two VLAN mapping configuration
example
Network requirements
As shown in Figure 55 , Site 1 and Site 2, two remote users in VPN A, are in VLAN 10. SP 1 assigns
VLAN 100 to VPN A, and SP 2 assigns VLAN 200 to VPN A.
Configure one-to-two and two-to-two VLAN mappings to enable the two sites to communicate across the
two SP networks.

# Set customer-side port GigabitEthernet 4/0/1 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. Apply uplink
policy test to the incoming traffic.
