Configuration Example

Figure 7-6 shows a configuration example that uses four HP switches to
establish a QinQ tunnel through the provider network.

Customer-network "ports (A1 and A2) accept all
tagged and untagged frames and put them into a
single S-VLAN per customer.
Figure 7-6. QinQ Configuration Example
The design parameters for this example are as follows:
The provider edge bridge and the provider core bridge are configured in
■
svlan mode.
■ Each customer is associated with a single S-VLAN connecting two sepa-
rate sites: customer A's VLANs (C-VLANs 1-10) are associated with
S-VLAN 100; and customer B's VLANs (C-VLANs 1-20) are associated with
S-VLAN 200.
■ The VLANs of customers A and B can overlap: this will not result in
intermixing of customer frames in the provider cloud because the
S-VLANs associated with each customer are different.
■ Core devices are not mandatory to establish a QinQ tunnel. For example,
two edge-bridges can be connected directly to create a provider bridge
network.
