[CE1-GigabitEthernet0/0/0.1] vlan allow-pass vid 10 to 50
Step 3 Configure an interface on CE connected to a PE to add a VLAN tag to user packets.
# Configure an interface on CE1 connected to a PE to add a VLAN tag to user packets. The
configuration of CE2 is similar to that of CE1.
[CE1-GigabitEthernet0/0/0.1] vlan dot1q-tunnel 20
[CE1-GigabitEthernet0/0/0.1] quit
Step 4 Add interfaces on PEs to VLAN 20 in trunk mode. The configurations of PE2 and P are similar
to the configuration of PE1.
# Add GE0/0/0 and GE0/0/1 on PE1 to VLAN 20 in trunk mode.
<Huawei> system-view
[Huawei] sysname PE1
[PE1] vlan batch 20
[PE1] interface gigabitethernet 0/0/0
[PE1-GigabitEthernet0/0/0] port link-type trunk
[PE1-GigabitEthernet0/0/0] port trunk allow-pass vlan 20
[PE1-GigabitEthernet0/0/0] quit
[PE1] interface gigabitethernet 0/0/1
[PE1-GigabitEthernet0/0/1] port link-type trunk
[PE1-GigabitEthernet0/0/1] port trunk allow-pass vlan 20
[PE1-GigabitEthernet0/0/1] quit
Step 5 Verify the configuration.
# On a PC in a VLAN of a branch in enterprise A, ping a PC in the same VLAN of the other
branch in enterprise A. The ping operation succeeds, indicating that devices transmitting the
same service can communicate with each other.
