Onboard Session Smart Routers for WAN Configuration

In a Juniper Mist™ network, you must onboard your Juniper® Session Smart™ Routers by assigning them to sites. Complete the onboarding by attaching hub profiles and spoke templates to the respective hub sites and spoke sites. This final step brings the topology together.

Before You Begin

We assume that you have your Session Smart Router already onboarded to the Juniper Mist™ cloud. We also assume that the physical connections such as cabling are already in place and that you are using valid interfaces and VLANs in your sandbox.

For details on getting your Session Smart Router up and running in the Mist cloud, see SSR Series Devices.

Assign Spoke Templates to Sites

The template that you created in Configure WAN Edge Templates now exists in the Juniper Mist cloud as an object that you can assign to one or more sites. WAN edge templates are a quick and easy way to group the common attributes of WAN edge spoke devices. You can apply a single template to multiple sites. Any changes to the WAN edge template are applied to all the sites without any additional steps.

If a site already has a template assigned to it, assigning another template will replace the existing template. That is, one site cannot have two templates, and the newer template will overwrite the older template.

To assign a WAN edge spoke template to a site:

  1. In the Juniper Mist portal, select Organization > WAN > WAN Edge Templates and select the required template.
  2. Scroll to the top of the WAN Edge Templates page, and click Assign to Sites.

  3. In the Assign Template to Sites window, select the required sites and click Apply.

The WAN Edge Templates page reflects the updated status. Figure 3 indicates that three sites are using the template.

Assign a Session Smart Router to a Site

To assign your Session Smart Router to sites, the devices must be present in the Juniper Mist inventory. You can claim or adopt your Session Smart Router to onboard it in the Juniper Mist cloud. After the device is on board, the organization inventory shows the device. For details on onboarding, see Getting Started.

To assign a Session Smart Router to a site:

  1. In the Juniper Mist portal. click Organization > Admin > Inventory.
  2. Refresh your browser and check under WAN Edges to find out if your Session Smart Router is part of the inventory.

  5. Enable the Manage configuration with Mist option.

    Figure 7 shows changes in the inventory once you assign the device to the site.

Assign a Hub Profile to the Session Smart Router

A hub profile comprises the set of attributes that are associated with a particular hub device. Each hub device in a Juniper Mist™ cloud topology must have its own profile. You apply the hub profile to an individual device that’s at a hub site.

To assign a hub profile to the Session Smart Router, which is part of a hub site:

  1. In the Juniper Mist portal, click Organization > WAN > Hub Profiles. The Hub Profile displays the list of existing profiles.
  2. Click the hub profile that you want to assign to a site.
  3. Under the Applies To option, select the site from the list of available sites.

  4. Click Save to continue.
  5. Repeat the same steps to add more hub sites. You can see the result on the Hub Profiles page.

Revert Configuration Automatically for Session Smart Router

Once the Session Smart Router is adopted or claimed, it automatically receives new configurations from the Juniper Mist portal. If a new configuration is invalid, the device rejects it and returns to the last valid configuration. If valid, the configuration is applied to the router. The router then waits five minutes and checks the connection to the Mist cloud. If it loses connectivity after this period, the Mist portal rolls back to the previous configuration. This auto-rollback feature ensures the system quickly returns to a working configuration.
