The VRF in ACI is identical to a VRF in traditional networking. It contains layer 3 routing instances, tables, and IPs. VRFs must have a unique within their tenant, but do not need to be globally unique. VRF’s are joined to the tenant in which they are created and cannot be separated from their tenant. A ‘show vrf’ command in the ACI CLI will show all of the VRFs and which tenant they are in. If you are reviewing ACI documentation, keep in mind that VRFs were under different names in previous versions, such as “Contexts” or “Private Networks”.
