DES-7200 Configuration Guide Chapter 12 QinQ Configuration
12-37
12.4.3 Configuration tips
1. Enabling basic QinQ on the provider edge devices (Provider S1 and Provider
S2) will meet the first need.
2. Enabling STP transparent transmission on provider edge devices (Provider
S1 and Provider S2) will allow the provider network to transmit STP packets
from user network through BPDU tunnel.
Note
In QinQ configuration model, when the
service-network-connecting uplink port of edge device or the
interconnecting ports of service provider devices are Trunk
ports or Hybrid ports, please don't set the native vlan of trunk
ports or hybrid ports to the default vlan of tunnel port,
because packets leaving the trunk port or hybrid port will be
stripped off the Tag with VID being its native vlan.
12.4.4 Configuration Steps
z Configure Provider S1
Step 1: Create provider VLAN 200
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#vlan 200
DES-7200(config-vlan)#exit
Step 2: Enable basic QinQ on the interface connecting to the user network, and
use VLAN 200 to transmit the traffic of user network through tunnel.
DES-7200(config)#interface gigabitEthernet 0/1
DES-7200(config-if-GigabitEthernet 0/1)#switchport mode dot1q-tunnel
DES-7200(config-if-GigabitEthernet 0/1)#switchport dot1q-tunnel native vlan
200
DES-7200(config-if-GigabitEthernet 0/1)#switchport dot1q-tunnel allowed
vlan add untagged 200
Step 3: Enable STP transparent transmission on the interface connecting to the
user network.
DES-7200(config-if-GigabitEthernet 0/1)#l2protocol-tunnel stp enable
DES-7200(config-if-GigabitEthernet 0/1)#exit
Step 4: Enable global STP protocol transparent transmission.
DES-7200(config)#l2protocol-tunnel stp
