SD-WAN Sites

 

A typical SD-WAN site topology includes an on-premise spoke site and a hub site. A hub site can be an enterprise hub site, which is an SD-WAN site that is used to carry site-to-site traffic between on-premise spoke sites and to break out backhaul (central breakout) traffic from on-premise spoke sites.

An on-premise spoke site represents an endpoint that is part of a customer premise equipment (CPE) at some physical location such as a branch office or a point-of-sale (PoS) location. Typically, these points are connected using overlay connections to hub sites.

CSO Release 5.0.0 supports SD-WAN sites that contain an EX Series switch for the branch network along with the CPE device.

You can Add an Enterprise Hub Site for SD-WAN Deployments and one or more of the following on-premise spoke sites for SD-WAN:

Add an Enterprise Hub Site for SD-WAN Deployments

An enterprise hub is an SD-WAN site that is used to carry site-to-site traffic between on-premise spoke sites and to break out backhaul (central breakout) traffic from on-premise spoke sites.

Note

You can add enterprise hubs only if the SD-WAN mode is set to real-time optimized.

To add an enterprise hub:

  1. On the Sites page (Resources > Site Management) of the CSO portal, click Add, and select Enterprise Hub.

    The Add enterprise hub for Tenant-Name page appears.

  2. Complete the configuration settings according to the guidelines provided in Table 1.
  3. Click OK.

    When the site is successfully created, the Site Status on the Sites page changes to Provisioned.

Add an Enterprise Hub Site with SD-WAN and LAN Capabilities

An enterprise hub is an SD-WAN site that is used to carry site-to-site traffic between on-premise spoke sites and to break out backhaul (central breakout) traffic from on-premise spoke sites. You can add an EX Series switch for branch network as part of the enterprise hub site. The following illustration shows a simple topology that contains an enterprise hub and an EX Series switch.

To add an enterprise hub:

  1. On the Sites page (Resources > Site Management) of the CSO portal, click Add, and select Enterprise Hub.

    The Add enterprise hub for Tenant-Name page appears.

  2. Complete the configuration settings according to the guidelines provided in Table 2.
  3. Click OK.

    The site activation job is initiated and the Site Activation: Site-Name page appears displaying the progress of the steps executed for activating the devices in the site.

  4. To activate the switch, you must manually configure the stage-1 configuration on the switch.

    1. On the Site Activation page, after the Prestage Device step completes successfully for the switch, the View Stage-1 Configuration link appears next to the Prestage Device step.
    2. Click the View Stage-1 Configuration link.

      The Stage-1 Configuration page appears displaying the stage-1 configuration.

    3. Copy the stage-1 configuration and log in to the CLI of the EX Series switch.
    4. Enter the configuration mode, paste, and commit the configuration.

      After the stage-1 configuration is committed, the switch has the outbound SSH configuration to connect with CSO. CSO then executes the bootstrap and provisioning processes on the switch and completes provisioning the switch.

When the site is successfully created, the Site Status on the Sites page changes to Provisioned.
