Add a Provider Hub Device

 

A provider hub device resides in a POP within the SP or OpCo network. Provider hub devices are shared amongst multiple tenants through the use of virtual routing and forwarding (VRF) instances configured on the provider hub itself. They allow site-to-site traffic to flow in hub-and-spoke deployments, serve as OAM gateway devices for management traffic between CSO and CPE devices, and can serve as backup data hubs when an enterprise hub device is used in a tenant.

Provider hubs come in three varieties: OAM_ONLY, DATA_ONLY, or OAM_AND_DATA.

  • OAM_ONLY and OAM_AND_DATA hubs pass OAM traffic between CSO and the CPE devices. CPE devices connect to these OAM-capable hubs over IPSec. In the CSO on-premises installation, the SP administrator adds the OAM-capable hubs. In CSO SaaS, the OAM-capable hubs are provided (by Juniper Networks) as part of the service.

  • DATA_ONLY and OAM_AND_DATA hubs route site-to-site user traffic in a hub-and-spoke topology. These data-capable provider hubs are optional. In the CSO on-premises installation, the SP or OpCo administrator creates the data-capable hubs. In CSO SaaS, the OpCo administrator creates the data-capable hubs.

Best Practice

It is recommended that all provider hubs be clearly named for their data and OAM capabilities.

Note
  • For SD-WAN, we recommend that you configure two OAM-capable provider hubs to provide redundancy in the OAM network. In CSO SaaS, Juniper Networks provisions two OAM-capable hubs by default. In the CSO on-premises version, the SP Administrator must add the OAM-capable hubs.

  • Before you add the provider hub, check the cable connections, review the NAT and firewall ports and protocols, and check the Junos OS version of the enterprise hub device, as explained in Supported Devices for SD-WAN, and Ports and Protocols to Open.

To add a provider hub device:

  1. Select Resources > Provider Hub Devices.

    The Provider Hub Devices page appears.

  2. Click the add (+) icon.

    The Add Provider Hub page appears, displaying the General settings to configured.

  3. Configure the General settings as explained in Table 1, and click Next.

    You are taken to the WAN section of the wizard.

    Note

    Fields marked with an asterisk (*) are mandatory.

  4. Configure the WAN settings as explained in Table 2 and click Next.

    You are taken to the Summary section of the wizard.

  5. Review the configuration in the Summary tab, and modify the settings, if required.

    You can also download the settings that you configure as a JavaScript Object Notation (JSON) file by clicking the Download as JSON link at the bottom of the page

  6. Click OK.
    • If you entered a serial number during activation and automatic activation is enabled, the Site Activation Progress page appears. The site activation process proceeds through the tasks explained in Site Activation Tasks and Troubleshooting.

      Click OK to close the page.

      Note

      If you don’t want to wait for the provider hub activation to finish, you can close the page and monitor the status of the activation from the Jobs page (Monitor > Jobs).

      The time taken for provider hub activation varies depending on the device that CSO is activating.

    • If you did not enter a serial number or if automatic activation is disabled, you are returned to the Provider Hub Devices page. CSO triggers a job and displays a confirmation message with a job link. Click the link to view the status of the job.

      After the job is finished, CSO displays a confirmation message with a job link. The status of the site changes to CREATED. You must manually activate the device to finish the activation process. To manually activate the provider hub:

      1. Select the device and click Activate Device.

        The Activate Site page appears.

      2. If a serial number was not specified when the site was added, enter the serial number of the device in the Serial Number field. Serial numbers are case sensitive.

        If the serial number that you entered is already present in the system, CSO displays an error message. If the serial number is not present, then CSO displays a green check mark.

      3. If automatic activation was disabled when the site was added, enter the activation code of the device in the Activation Code field.
      4. Click OK.

        CSO triggers a job and the Site Activation Progress page appears after a few seconds. Because the site was previously modelled, the Ship Device task is the first task to be executed. The rest of the steps are as explained in Site Activation Tasks and Troubleshooting.

Tip

After you add a provider hub, you can modify certain parameters for DATA_ONLY provider hubs. For more information, see the Edit Provider Hub Site Parameters topic in the CSO Administration Portal User Guide (available on the CSO Documentation page).

Table 1: General Settings (Add Provider Hub [Device] Page)

Field

Guideline

Site Information

 

Site Name

Enter a name for the provider hub device. The name can contain alphanumeric characters and hyphens (-) and must not exceed 15 characters. For example, LA-PHub-OAM

Management Region

Displays regional as the management region. You cannot modify this field.

Site Capability

Select the capability of the provider hub device:

  • OAM_ONLY—Transmits only OAM traffic.

    Note: This option is available only for SP Administrator users in the on-premises version of CSO.

  • DATA_ONLY—Transmits only data traffic.

  • OAM_AND_DATA—Transmits both data traffic and OAM traffic.

For provider hubs added with data only capability, CSO establishes a secure OAM tunnel between the provider hub with data capability and a provider hub with OAM_ONLY or OAM AND DATA capability).

POP

Select the POP to which you want to assign the provider hub device.

Authentication Type

Select the type of authentication to use for establishing secure IPsec tunnels:

  • Pre-shared key, which is the default.

  • Public Key Infrastructure

Table 2: WAN Settings (Add Provider Hub [Device] Page)

Field

Guideline

Device Series

Displays SRX as the device series because currently only SRX Series devices are supported as provider hubs.

[Device Template]

Ensure that you select the correct device template for the provider hub device from the carousel. For example, for an SRX1500 device, you can select SRX as SD-WAN Hub (or a modified version of that template) as the device template.

Note: Check that the interface names in the device template match the ones on the device that you’re using.

Device Information

 

Serial Number

If you want CSO to proceed with the provider hub activation immediately after you complete the add provider hub workflow, enter the serial number. If the serial number that you entered is already present in the system, CSO displays an error message. If the serial number is not present, then CSO displays a green check mark.

If you want CSO to only model the provider hub, leave this field blank. If you don’t enter a serial number, you must manually activate the provider hub later.

Auto Activate

Automatic activation is typically enabled by default (based on the setting in the device template). When automatic activation is enabled, zero-touch provisioning (ZTP) of the provider hub device is automatically triggered after the site is added to CSO.

If you want the device to be activated manually, click the toggle button to disable automatic activation.

Activation Code

If you disabled automatic activation, enter the activation code that must be entered when the device is manually activated later.

When you manually activate the device later, CSO checks the activation code entered against the activation code specified here and activates the device only if the activation codes match.

Boot Image

If you want to upgrade the provider hub device with the latest supported Junos OS version, select the boot image from the list. The boot image is used to upgrade the device when CSO starts the zero touch provisioning (ZTP) process. If you don't specify a boot image, which is the default option (Use Image on Device) in the list, then the CSO skips the procedure to upgrade the device during ZTP.

Management Connectivity

 

Loopback IP Prefix

By default, CSO assigns the IPv4 address prefix for the loopback interface on the device.

OAM Interface

For provider hubs with OAM or OAM and data capabilities, select the interface on the provider hub device that you want to use to connect the provider hub device to CSO. This interface is used only for OAM connectivity.

The interface names are listed are the names configured in device template.

OAM VLAN

For provider hubs with OAM or OAM and data capabilities, enter an OAM VLAN ID for in-band management of the hub device. If you specify an OAM VLAN ID, then in-band OAM traffic reaches the device through the selected OAM interface.

OAM IP Prefix

For provider hubs with OAM or OAM and data capabilities, enter an IPv4 address prefix for the OAM interface in the provider hub device. The prefix must be unique across the entire management network.

OAM Gateway

For provider hubs with OAM or OAM and data capabilities, enter the IP address of the next-hop through which the connectivity from the provider hub device to CSO is established.

EBGP Peer-AS

For provider hubs with OAM or OAM and data capabilities, enter the autonomous system (AS) number of the external BGP (EBGP) peer. The AS number is unique to the service provider and is needed to establish the EBGP peering session.
