deployment topology filter icon on the top right of the screen to display additional deployment topology options. The

output from these screens and the Deployment Topology and Fabric Customization screens create a network topology

and the detailed wiring plan. See also Deployment Topology Use Cases.

Based on your design requirements you can create a 1, 2, or 3 tier topology as shown below

• Tier 1 Topology — Contains 2 switches and a downlink and uplink configuration. There are no fabric links.

Figure 27. VLT 1 Tier Topology: Aggregation Layer

For more information about the tier 1 topologies, see Designing a Layer 2 VLT and Layer 3 with Resiliency (Routed

VLT) Fabric.

• Tier 2 Topology — Contains 2 layers of switches, has fabric interlinks, uplinks and downlinks. Distributed Core (spine

and leaf) or VLT (aggregation and access). For more information about tier 2 topologies, see Designing a Layer 2 VLT

and Layer 3 with Resiliency (Routed VLT) Fabric and Selecting a Layer 3 Distributed Core Fabric Design.

• Tier 3 Topology — Layer 3 with Resiliency (Routed VLT) has 3 layers of switches, fabric interlinks, uplinks and

downlinks. For more information about the tier 3 topologies, see Designing a Layer 2 VLT and Layer 3 with Resiliency

(Routed VLT) Fabric .
