Creating a Hub-and-Spoke topology

Expand all | Collapse all

A Hub-and-Spoke topology is built using roles that you assign to CPE devices. You can assign the role of a standard CPE device or an SD-WAN Gateway. Standard devices establish tunnels with each other through SD-WAN Gateways.

By default, all devices are assigned the standard device role. To build a Hub-and-Spoke topology, at least one device must be assigned the SD-WAN Gateway role.

You can assign a role in a CPE template or to an individual device. When you assign a role in a CPE template, the role is automatically assigned to all devices that are using that template. To build a Hub-and-Spoke topology, use the following instructions:

• Assigning a role in a CPE template.

  To assign a role in a CPE template:

  1. In the menu, go to the SD-WAN → CPE templates subsection.

     A table of CPE templates is displayed.

  2. Click the CPE template.

     The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Information tab is selected, which displays general information about the CPE template.

  3. Select the Topology tab.

     The topology tag settings are displayed.

  4. In the Role drop-down list, select the role:
     • CPE for a standard CPE device.
     • Gateway for an SD-WAN Gateway.
  5. In the upper part of the settings area, click Save to save CPE template settings.
• Assigning a role to an individual CPE device.

  To assign a role to an individual CPE device:

  1. In the menu, go to the Infrastructure section.

     This opens the resource management page. By default, the Network resources tab is selected, which displays the table of SD-WAN and SDN Controllers.

  2. Click Management → Configuration menu next to the SD-WAN Controller.

     This opens the Controller configuration menu. By default, you are taken to the Controller nodes section, which displays a table of Controller nodes.

  3. Go to the Topology tags section.

     The topology tag settings are displayed.

  4. In the Switch drop-down list, select the CPE device.
  5. In the Role drop-down list, select the role:
     • CPE for a standard CPE device.
     • Gateway for an SD-WAN Gateway.
  6. In the upper part of the page, click Save.

  You can also assign a role in the CPE device configuration.

  To assign a role in the CPE device configuration:

  1. In the menu, go to the SD-WAN → CPE section.

     A table of CPE devices is displayed.

  2. Click the CPE device.

     The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, which displays the current configuration of the CPE device. This tab also displays the table of Out-of-band management CPE device configurations.

  3. Select the Topology tab.

     The topology tag settings are displayed.

  4. Select the Override check box to ignore the applied CPE template and make the settings in the selected tab editable. This check box is cleared by default.
  5. In the Role drop-down list, select the role:
     • CPE for a standard CPE device.
     • Gateway for an SD-WAN Gateway.
  6. In the upper part of the settings area, click Save to save CPE device settings.
