Figure 19. Two-Tier VLT Topology: Aggregation and Access Layer

Figure 20. 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 21. 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. From the menu, click Network and then the Design Fabric tab.

2. Click New Fabric.

3. Navigate to the Deployment Topology screen.

4. 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.
