2.1.1 Selective QinQ Overview
Selective QinQ is an enhanced application of the VLAN-VPN feature. With the selective
QinQ feature, you can configure inner-to-outer VLAN tag mapping, according to which
you can add different outer VLAN tags to the packets with different inner VLAN tags.
The selective QinQ feature makes the service provider network structure more flexible.
You can classify the terminal users on the port connecting to the access layer device
according to their VLAN tags, and add different outer VLAN tags to these users. In the
public network, you can configure QoS policies based on outer VLAN tags to assign
different priorities to different packets, thus providing differentiated services. See
Figure

for details.
