Figure 3 shows the example lab setup that is used in this guide. The lab setup illustrates the repatriation use case where the customer is bringing back storage and servers from the cloud. Two Dell S5248F-ON switches are configured as leaf switches in two different racks. They are each connected to the Data Center Cloud with a 100 GbE port that is configured as a trunk port with allowed VLANs.

Three tenants are enabled with VRFs in each switch. The default VRF (in yellow) has interfaces for existing corporate resources that are assigned to it. Logical and physical interfaces are assigned by default to the default VFR. The sales VRF is created with loopback 1 and VLAN 20 and VLAN 200 interfaces that are assigned to it. The marketing VRF is created and loopback 2 and VLAN 30 and VLAN 300 are created and assigned to it.

The loopback interfaces assigned to each VRF simulates end hosts. Each tenant has unique VLAN interfaces but use overlapping IP addresses that are inherited from the cloud on their respective VLANs. A trunk is configured in each switch to connect the switch to the Data Center Cloud and to each other.
