Auto VNI simplifies the mapping IDs by using the VLAN ID as the VNI ID, for example VLAN 100 = VNI 100.
This method of mapping works well in environments where overlapping VLANs are not being used. However, if two different tenants are using VLAN 100, VNI 100 cannot be used by both. At this point, manual mapping of VLAN to VNI is required. Extreme Fabric Automation simplifies this process by allowing VNI ranges for tenants to automate “manual” mapping to work for overlapping VLANs.
