5.20 QinQ Configuration

QinQ Overview
A QinQ is the IEEE 802.1Q tunneling protocol and is also called VLAN stacking. The 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.
A QinQ does not need any protocol support. The simple Layer 2 Virtual Private Network
(L2VPN) can be realized through QinQ. The QinQ is especially suitable for the small-sized
LAN that takes the layer-3 switch as its backbone.
For the typical network of the QinQ technology, see
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).

Figure 5-24 Typical QinQ Network

The user network is connected to the PE through the Trunk VLAN mode. The internal
Uplink ports of the ISP network are symmetrically connected through the Trunk VLAN
mode.
1. When a packet is sent form user network 1 to the customer port of switch A, because
the PORTBASE VLAN-based customer port does not identify the tag when receiving
the packet, the customer port processes the packet as an untagged packet no matter
whether this data packet is attached with the VLAN tag or not. The packet is forwarded
by the VLAN 10, which is determined by the PVID.
2. The uplink port of switch A inserts the outer tag (VLAN ID: 10) when forwarding the
data packet received from the customer port. The tpid of this tag can be configured
