Deploy a Citrix SD-WAN™ VPX instance on a Citrix® ADC SDX appliance
Citrix SD-WAN technology applies software-defined networking (SDN) concepts to WAN connections. The technology abstracts traffic management and monitoring from network hardware and applies them to individual applications. The result is improved performance, high-quality user experiences over geographically dispersed locations, and simplified deployment of wide-area and cloud-access networks. For more information, see Citrix SD-WAN.
From release 12.1 49.xx, you can deploy a Citrix SD-WAN VPX instance on Citrix ADC SDX 14XXX and SDX 115XX appliances. For more information, see the following documents:
- 
    
Citrix ADC SDX 14020, SDX 14030, SDX 14040, SDX 14060, SDX 14080, and SDX 14100
 - 
    
Citrix ADC SDX 11515, SDX 11520, SDX 11530, SDX 11540, and SDX 11542
 
Note
Only SD-WAN VPX Standard edition is supported. For more information, see SD-WAN VPX editions.
Deploying a Citrix SD-WAN VPX instance on an SDX appliance includes the following tasks:
- Installing the hardware: ensure the SDX hardware is properly installed. For more information, see Installing the Hardware.
 - Setting up and configuring the SDX Management Service. For more information, see Getting Started with the Management Service User Interface and Configuring the Management Service.
 - Provisioning the SD-WAN VPX instance on the SDX appliance. For more information, see Provision the Citrix SD-WAN VPX instance on a Citrix ADC SDX.
 - Configuring the SD-WAN VPX instance. For more information, see the Configuration documentations and Configuring the virtual path service between the MCN and client sites.
 
Prerequisites
Ensure you’ve the following licenses:
- Citrix SD-WAN VPX license
 - Citrix ADC SDX platform license
 
Citrix SD-WAN VPX requirements
The Citrix SD-WAN VPX on SDX platform can act both as a site and MCN. The MCN can handle 1 Gb/s bidirectional throughput and 64 sites.
Supported throughput for MCN and site
- 250 Mb/s to 1 Gb/s bidirectional throughput
 - MCN supports 64 sites
 
Hardware requirement for supported throughput
Site
- 4 CPUs to 16 CPUs
 - 4 GB to 16 GB RAM
 - 60 GB to 250 GB disk storage
 - Minimum 4 NICs: one for management and remaining minimum 3 for data path
 
Master control node (MCN)
- 4,8, and 16 CPUs
 - 16 GB RAM
 - 250 GB disk storage
 - Minimum 4 NICs: one for management and remaining 3 for data path, with dedicated NICs for data path
 
Data center topology
You can deploy a Citrix SD-WAN VPX appliance on a Citrix ADC SDX in policy-based route (PBR) mode or in inline mode. See scenario 1 and 2 for topologies for these two supported modes. For more information, see Deploying SD-WAN in PBR mode (Virtual Inline Mode).
Scenario 1. Data center topology: PBR mode or virtual inline mode

Scenario 2. Branch topology: Inline mode

Provision the Citrix SD-WAN VPX instance on a Citrix ADC SDX
Before you provision the Citrix SD-WAN VPX appliance, download the SD-WAN VPX image from the Citrix product download site.
Follow these steps to provision the Citrix SD-WAN VPX appliance.
- Log on to the Citrix ADC SDX appliance.
 - Navigate to Configuration > SD-WAN > Instances.
 - 
    
Select Software Images > Upload and upload the SD-WAN XVA file.

 - 
    
Select Instances > Add. The Provision SD-WAN Instance page appears.
 - In the Provision SD-WAN Instance page, enter the following:
    
- Name
 - IP address
 - Netmask
 - Gateway address
 - Upload the XVA file
 - Under Resource Allocation, allocate resources.
 
 - Under Network Settings, provision management interfaces and select OK to create to provision the SD-WAN VPX instance on the SDX appliance.
 
 
Note The SDX Management Service binds interfaces to the VPX instance in ascending sequence of interface names. For example, if you add 1/4, and 1/1, Management Service arranges them as 1/1, 1/4. When you add new interfaces, the existing sequence is retained and a new sequence is created. For example, you add interfaces 1/2, 10/1, 1/3.The new sequence would be 1/1, 1/4; 1/2, 1/3, 10/1.
 - 
    
The SD-WAN VPX instance appears under the Instance page. Here’s an example.

 
To edit the instance, navigate to Configuration > SD-WAN > Instances. Select and click the instance. Once you’ve completed editing, click OK to save the changes.
Configuring the Citrix SD-WAN VPX instance
After you’ve created an SD-WAN instance on the SDX appliance, configure the SD-WAN instance by completing these two tasks:
- 
    
Apply configuration for both MCN and site appliances.
 - 
    
Configure virtual path and transmit traffic.
