Support for Multiple VRFs Under Single VNet
 Note |
The following content refers to "Multi-Site Orchestrator" which has been rebranded to Nexus Dashboard Orchestrator. Same information is applicable to both products. |
Beginning with Release 5.1(2), the ability to carve out multiple VRFs has been extended beyond the infra VNet so that you can divide any VNet into multiple VRFs under the same tenant, where multiple VRFs can exist in a single VNet. This is useful for situations such as cloud service access, where you might want to carve out multiple networks (VRFs) within a given VNet, allowing you to have separate routing by having unique route tables for each VRF within the VNet in the cloud.
The following graphic shows an example manged object (MO) relationship tree with multiple VRFs under the same tenant (VNet).
In this example, two VRFs exist under the same tenant (VNet):
-
The primary VRF with the name
mainVRF -
A secondary VRF with the name
servicesVRF
A second CIDR block and subnet exists in the same cloud context profile, under the same tenant (VNet), but that second CIDR block and subnet is associated with the secondary VRF in that same VNet.
Configuring Multiple VRFs Under a Single VNet in Cisco ACI Multi-Site Orchestrator
The following procedures describe how to configure multiple VRFs under a single VNet to create the configuration that was described in Support for Multiple VRFs Under Single VNet, where two VRFs exist under the same tenant (VNet):
-
The primary VRF with the name
mainVRF -
A secondary VRF with the name
servicesVRF
