Three-Tier Topologies for a 10 Gb or 40 Gb ToR (mVLT) Deployment Layer 2 or Layer 3 with
Resiliency (Routed VLT)
Use the following tables as a guideline for selecting the appropriate three-tier Layer 2 VLT or Layer 3 with
Resiliency (Routed VLT) fabric design for a 40 Gb Tor (mVLT) Deployment.
NOTE: With a Layer 2 VLT fabric, the uplinks come from the switches on the aggregation side. For
information about tiers, refer to Deployment Topology.
AVC = Aggregation VLTi Capacity
CVC = Core VLTi Capacity
BW = Bandwidth
DL = Downlink
DL BW = Downlink Bandwidth
FL BW CA = Fabric Link Bandwidth between Core & Aggregation
FL BW AA = Fabric Link Bandwidth between Aggregation & Access
UL BW = Uplink Bandwidth
