Spanning the VLANs in an eVLT architecture could interconnect and aggregate multiple racks with the same VLAN. Withrouted VLT, you can configure a VLAN as layer 3 in a VLT domain and as layer 2 VLAN in all other VLT domains. By configuring a VLAN aslayer 3 in a VLT domain and as layer 2 VLAN in all other VLT domains, you can confine the ARP entries to one particular VLT domain.At the core/aggregation layer VLT domain, you can configure common layer 3 VLANs for inter VLAN routing within the VLT domain.VLT on Core SwitchesUplinks from servers to the access layer and from access layer to the aggregation layer are bundled in LAG groups with end-to-end Layer 2multipathing. This set up requires “horizontal” stacking at the access layer and VLT at the aggregation layer such that all the uplinks fromservers to access and access to aggregation are in Active-Active Load Sharing mode. This example provides the highest form of resiliency,scaling, and load balancing in data center switching networks.The following example shows stacking at the access, VLT in aggregation, and Layer 3 at the core.922 Virtual Link Trunking (VLT)
