A connection must be established between your Microsoft Azure network and your on-prem NSX-T Data Center appliances.
- Connect your Microsoft Azure subscription with on-prem NSX-T Data Center.
- Configure your VNets with the necessary CIDR blocks and subnets required by NSX Cloud.
- Synchronize time on the CSM appliance with the Microsoft Azure Storage server or NTP.
Connect your Microsoft Azure subscription with on-prem NSX-T Data Center
Configure your VNet
In Microsoft Azure, create routable CIDR blocks and set up the required subnets.
- One management subnet with a recommended range of at least /28, to handle:
- control traffic to on-prem appliances
- API traffic to cloud-provider API endpoints
- One downlink subnet with a recommended range of /24, for the workload VMs.
- One, or two for HA, uplink subnets with a recommended range of /24, for routing of north-south traffic leaving from or entering the VNet.
See NSX Public Cloud Gateway: Architecture and Modes of Deployment for details on how these subnets are used.
