Le QinQ sélectif, également appelé empilement de VLAN ou QinQ, est implémenté en fonction d'interfaces et de VLAN.
Configurez le périphérique pour qu'il identifie le VLAN 2 dans la balise externe des paquets avec les VLAN 100 à 200 dans les balises internes, puis qu'il balise le VLAN 3 dans la balise externe des paquets avec les VLAN 300 à 400 et qu'il transmet de manière transparente les paquets du VLAN 1000.
- Configurez le QinQ sélectif sur un commutateur fixe.# Create VLAN 2, VLAN 3, and VLAN 1000.
