Figure 16. Two-Tier VLT Topology: Aggregation and Access Layer

Figure 17. Two-Tier Distributed Core Topology: Spine and Leaf

• Three-Tier Topology — Layer 3 with Resiliency (Routed VLT). Has three layers of switches, fabric

interlinks, uplinks and downlinks. For more information about three-tier topologies, refer to Designing

a Layer 2 VLT and Layer 3 with Resiliency (Routed VLT) Fabric.

Figure 18. Three-Tier VLT Topology Core: Aggregation - Access Layer

The following illustration and table describe the deployment types for a fabric.

NOTE: For more information about topologies, refer to the Designing a Layer 2 VLT and Layer 3

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

Selecting a Fabric Deployment Type

1. Navigate to the Network > Design Fabric > New Fabric > Deployment Topology screen.

2. In the Fabric Type area, select one of the following fabric types:

• Layer 2 — Use the Layer 2 VLT fabric for workload migration over virtualized environments. For

more information, refer to VLT and Selecting a Layer 2 VLT and Layer 3 with Resiliency (Routed

VLT) Fabric Design.

• Layer 3 — Use the Layer 3 distributed core for large fabric deployments. For more information,

refer to Conventional Core Versus Distributed Core.

• Layer 3 with Resiliency (Routed VLT) — Use the Layer 3 fabric to extend equal cost multipathing

capabilities. For more information, refer to Selecting a Layer 2 VLT and Layer 3 with Resiliency

(Routed VLT) Fabric Design.
