Double VLANs
This section describes how to enable the double DVLAN feature. Double VLANs pass traffic
from one customer domain to another through the metro core. Custom VLAN IDs are
preserved and a provider service VLAN ID is added to the traffic so the traffic can pass the
metro core in a simple and cost-effective manner. You can use VLANs to specify customer
ports and a service provider port. In this example, the switches have the same configuration.

Figure 52. Double VLANS
The following example shows how to configure the NETGEAR switch shown in the preceding
figure to add a double VLAN tag for traffic going from the subnet domain connected to port
1/0/24. This example assumes that a Layer 2 switch connects all these devices in your
domain. The Layer 2 switch tags the packet going to the NETGEAR switch port 1/0/24. The
example is shown as CLI commands and as a web interface procedure.
