8.1.9 QinQ VLAN Mapping
QinQ or Double Tagging is one way for tunneling between several networks.
Fig. 8.3 Example of QinQ Configuration
If QinQ is configured on the V5808, it transmits packets adding another Tag to original
Tag. Customer A group and customer B group can guarantee security because
telecommunication is done between each VLANs at Double Tagging part.
Double tagging is implemented with another VLAN tag in Ethernet frame header.
