22. Double VLANs and Private VLAN Groups 22 This chapter includes the following examples: • Double VLANs • Private VLAN Groups on page 343 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.
