Onboard Session Smart Routers with Static IP Address

In some cases, you might need to onboard Juniper® Session Smart™ Routers to Juniper Mist using only static WAN IP addresses. This procedure is particularly relevant when deploying sites that are connected solely through WAN circuits without dynamic address assignment via DHCP. In such situations, you can use one of the following options to onboard a Session Smart Router to the Mist cloud:

  • Lightweight Field ZTP
  • One-time Static Device Provisioning

Before You Begin

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

For the procedure to create the WAN Edge template, see Configure WAN Edge Templates.

Set Static Information in WAN Edge Template

During onboarding, the device must get a Mist cloud configuration with static WAN address details. Therefore, use a WAN Edge template with static IP configuration.

To configure static IP configuration in a WAN edge template:

  1. In the Juniper Mist portal, select Organization > WAN > WAN Edge Templates and select the required template.
  2. In a WAN edge template, scroll-down to WAN section and select the WAN interface.
  3. Select IP Configuration type as Static.

  4. Enter IP Address, Prefix Length, and Gateway details. To re-use the template across different sites, use unique variables for the static WAN IP address, prefix length, and gateway.
  5. Save the template and scroll to the top of the WAN Edge Templates page, and click Assign to Sites.
  6. Next, for the site having static WAN addresses where you wish to deploy the Session Smart Router, populate the variables with the correct static WAN IP Address, Prefix Length, and Gateway.

    With the Mist cloud provisioned with a site having the appropriate static WAN address information, the site is now ready for device onboarding.

Device Onboarding

If a new SSR device is shipped directly to the site without intermediate staging, use one of two methods to onboard and bring it into service.

Lightweight Field ZTP

The lightweight field ZTP method for device onboarding in a static WAN scenario requires temporarily connecting the Session Smart Router device to on-site connectivity. This connection provides dynamic address assignment via DHCP and temporary connectivity to Mist cloud. For example, connect the WAN port of the Session Smart Router device to a mobile wireless router carried by the installer. Alternatively, connect it to the LAN port of a site router about to be decommissioned.

  1. Claim the device to your Mist org inventory (if not done already), and power it on. For details, see SSR Series Devices.
  2. Connect the ge-0-0 WAN port to an on-site device providing DHCP and connectivity to the Mist cloud.
  3. In the Juniper Mist portal. click Organization > Admin > Inventory.
  4. Refresh your browser and check under WAN Edges to find out if your Session Smart Router is part of the inventory.
  5. Assign Session Smart Router to an individual site using the Assign to Site option.

    Ensure you select the Manage configuration with Mist option.

  6. In Juniper Mist portal, monitor WAN Edge events for the site to verify if the device connects to the Mist cloud, and receives the configuration.
    Note: Upgrade the device to fully apply and run the configuration from Mist cloud.
  7. After the configuration having the static WAN addressing is applied and the device disconnects from Mist, remove the connection to the device providing temporary connectivity, and ensure the WAN ports are connected to the appropriate static WAN links.
  8. When the configuration of static WAN addressing is applied, the device disconnects from the Mist cloud. Now, remove the temporary connectivity device (that is, temporary connection the Session Smart router to on-site connectivity as mentioned earlier in this section) and connect WAN ports to the correct static WAN links.
  9. Verify that the device reconnects to the Mist cloud using the static WAN links.

One-Time Static Device Provisioning

This method involves connecting to the local console of the device, and pasting in some one-time provisioning information including the static address.

  1. Claim the device to your Mist org inventory (if not done already), and power it on. For details, see SSR Series Devices.
  2. In the Juniper Mist portal. click Organization > Admin > Inventory.
  3. Refresh your browser and check under WAN Edges to find out if your Session Smart Router is part of the inventory.
  4. Assign Session Smart Router to an individual site using the Assign to Site option.

    Ensure you select the Manage configuration with Mist option.

  5. Connect a laptop or PC to the local serial console port of the Session Smart Router on the site.
  6. Enter the default Session Smart Router login information.
  7. Copy the following lines of configuration. You must change {{wan0_static_ip}}, {{wan0_prefix}}, and {{wan0_gateway}} in the text to the static address details for the site.
  8. Connect the device to the appropriate static WAN link.
  9. Locally on the device, you can verify the local link state and connectivity using commands such as show arp, show network-interface, and ping.
  10. In Juniper Mist portal, monitor WAN Edge events for the site to verify if the device connects to the Mist cloud, and receives the configuration..
    Note: Upgrade the device to fully apply and run the configuration from Mist cloud.
