QinQ Configuration
QinQ Overview
QinQ is the IEEE 802.1Q tunneling protocol and is also called
VLAN
stacking. QinQ technology is the addition of one more VLAN tag
(outer tag) to the original VLAN tag (inner tag). The outer tag can
shield the inner tag.
QinQ does not need the protocol support. The simple Layer 2 Vir-
tual Private Network (L2VPN) can be realized through QinQ. The
QinQ is especially suitable for the small-size LAN that takes the
layer 3 switch as its backbone.
Figure 45
shows the typical networking of the QinQ technology.
The port connected to the user network is called Customer port.
The port connected to the ISP network is called Uplink port. The
edge access equipment of the ISP network is called Provider Edge
(PE).
