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

For workload migration in virtualized environments, use a Layer 2 VLT fabric design. To extend equal cost

multipath capabilities, use the Layer 3 with Resiliency (Routed VLT) fabric .

AFM supports the following Layer 2 VLT and Layer with 3 with Resiliency (Routed VLT) fabric designs:

• One and Two Tier ToR 10 Gb for Layer 2 LAN/SAN for iSCSI Topologies

• One and Two Tier ToR 10 Gb for Layer 2 LAN/SAN for Fibre Channel Topologies

• One Tier for 10 Gb and 40 Gb ToR for Layer 2 and Layer 3 Resiliency (Routed VLT)

• Two Tier and Three Tier Topologies for 1 Gb ToR VLT Deployment for Layer 2 and Layer 3 with

Resiliency (Routed VLT)

• 10 Gb or 40 Gb ToR (mVLT)

• Two and Three Tier 10 Gb ToR (mVLT) Deployment Topologies for Layer 2 or Layer 3 with Resiliency

• Three Tier Topologies for a 10 Gb or 40 Gb ToR (mVLT) Deployment Layer 2 or Layer 3 with

Resiliency (Routed VLT)

• Two and Three Tier MXL Blade Topologies for Layer 2 and Layer 3 with Resiliency (Routed VLT)

• 10 Gb Blade Switch (MXL) VLT Deployment
