Connectivity with Citrix SD-WAN appliances

After configuring sites on SD-WAN Orchestrator for On-premises, establish connectivity between Citrix SD-WAN appliances on the sites with SD-WAN Orchestrator for On-premises. You can establish connectivity in one of the following ways:

  • One-way Authentication: The SD-WAN appliance authenticates SD-WAN Orchestrator for On-premises. On enabling one-way authentication, you must download the SD-WAN Orchestrator for On-premises certificate and upload it on the SD-WAN appliance.

  • Two-way Authentication: The SD-WAN authenticate each other using the exchanged certificates. On enabling two-way authentication, you must upload the SD-WAN appliance certificate on SD-WAN Orchestrator for On-premises and also SD-WAN Orchestrator for On-premises certificate on the SD-WAN appliance.

  • No Authentication: The connectivity is established between the SD-WAN Orchestrator for On-premises and SD-WAN appliances with no authentication. You need not use the SD-WAN Appliance or SD-WAN Orchestrator for On-premises Certificate. You can use No Authentication when you have a secure network such as MPLS.

Note

It is recommended to use only one-way authentication or two-way authentication. In the case of no Authentication, you have to choose the secure DNS server.

You can configure connectivity with each site manually or use the automated zero-touch deployment.

Note

Citrix SD-WAN 11.3.0 is the minimum sofware version required for an appliance to connect to SD-WAN Orchestrator for On-premises.

Zero-touch deployment

Zero-touch deployment is an automated process to configure connectivity between the appliances and SD-WAN Orchestrator for On-premises. The NITRO API running in the back-end handles download and upload of certificates. It downloads the certificate from SD-WAN Orchestrator for On-premises, logs in to the SD-WAN appliance, and uploads the certificate. It also downloads the SD-WAN appliance certificate and uploads it on SD-WAN Orchestrator for On-premises.

Note

Zero-touch deployment is supported on SD-WAN appliances running with the 11.2.1 release or later.

Zero-touch deployment supports only one-way authentication and two-way authentication. No authentication is not supported. If Authentication Type is enabled on Administration > Certificate Authentication page, then two-way authentication is established. If Authentication Type is disabled, then one-way authentication is established.

To configure Zero-touch deployment:

  1. Navigate to Administration > Site ZTD Settings, and click + Site.

  2. Select a site from the Site Name drop-down list and enter the Management IP address of the Citrix SD-WAN appliance.

  3. Enter the Username and Password.

  4. Select the Freshly Provisioned check box if you are adding a newly provisioned site and enter a New Password.

    NOTE

    For a newly provisioned site, it is mandatory to change the default password at the time of first login.

  5. Click + to add more sites.

  6. Click Add. The configuration status of the sites is displayed in the Auto Configured Sites section.

Manual Connectivity Configuration

While configuring connectivity manually, you must download the SD-WAN Orchestrator for On-premises certificate and upload it on each appliance in the network. It involves logging into each appliance manually for uploading the certificates.

To configure connectivity manually:

  1. Navigate to Administration > Certificate Authentication and enable Authentication Type.

    When Authentication Type is enabled, the SD-WAN appliance can connect to SD-WAN Orchestrator for On-premises only through Two-way Authentication. When Authentication Type is disabled, the SD-WAN appliance can connect to SD-WAN Orchestrator for On-premises either through No Authentication, One-way Authentication, or Two-way Authentication.

  2. Click Regenerate and Download the SD-WAN Orchestrator for On-premises certificate.

  3. Choose an appliance from the Appliance Certificate section and upload the corresponding certificate downloaded from the SD-WAN appliance. For detailed information on downloading the appliance certificate, see Citrix SD-WAN Orchestrator on-premises configuration on SD-WAN appliance.

    NOTE

    Only .pem file type is supported.

  4. Log on to the SD-WAN appliance UI, navigate to Configuration > Virtual WAN > On-prem SD-WAN Orchestrator. Upload the certificate downloaded from SD-WAN Orchestrator for On-premises. For detailed information, see SD-WAN Orchestrator for On-premises configuration on SD-WAN appliance.
