Step 1: Begin
This guide walks you through the steps to get your new, cloud-ready SSR120 up and running in the Juniper Mist AI cloud portal. You can onboard a single device using your mobile phone, or one or more devices using your computer. Once onboarded, we'll walk you through the steps to create a basic configuration.
Meet the SSR120
The Juniper Networks SSR120 network appliance is part of the SSR portfolio. The SSR120 features four 1 GbE ports, two 1 GbE RJ-45/SFP combo ports, 8 GB of memory, and a 120 GB enterprise-grade solid-state drive (SSD) for storage.
The SSR120 runs the FIPS 140-2 Level 1 compliant Session Smart Router (SSR) software, which provides secure and resilient WAN connectivity.
The SSR120 appliance is available in models with or without LTE support.

Onboarding Complete!
Fantastic, your device is in your inventory! To provision your SSR device with ZTP, log in to Mist and continue with WAN configuration.
WAN Configuration
To begin your WAN design, identify the network to be used for accessing applications over a LAN network segment.
Add a Network
-
Navigate to the WAN section of the organization sidebar menu, and select
Networks.
-
Select Add Networks in the upper right.
- Give the network a name.
-
Configure the network subnet as
192.168.1.0/24
. - Click Save at the bottom of the Edit Network side panel.
Applications
Next, describe the applications for the WAN to deliver, starting with the Internet.
Add an Application
- Navigate back to the WAN section of the organization sidebar menu, and select Applications.
-
Select Add Applications in the upper right.
- Name the application Internet.
-
Enter
0.0.0.0/0
, or an IPv4 address space in the IP Addresses configuration. - Click Save at the bottom of the Add Application side panel.
WAN Edge Templates
So far you have an SSR device waiting to be claimed, a network for your LAN, and an
Internet
application for your WAN to deliver.
A WAN Edge template ties them all together! The use of templates allow for re-usable and consistent configuration for every SSR device you deploy.
Create a Template
- Navigate back to the WAN section of the organization sidebar menu, and select WAN Edge Templates.
-
Select Create Template in the upper right.
- Name the template.
-
Click Create.
-
Enter NTP and DNS information to be used by the WAN edge device.
WAN
-
Scroll to the WAN section of the template, and select Add
WAN.
-
Name the WAN port
wan1
. -
Since you already plugged port 0 on the device into the Internet, enter
ge-0/0/0
to designate it as a WAN port. - Make sure IP Configuration is set to be learned from DHCP, and that Source NAT is enabled.
-
Click Add at the bottom of the Edit WAN
Configuration side panel.
LAN
-
Scroll to the LAN section of the template, and select Add
LAN.
- From the Network drop-down menu, select your network segment to associate it with the LAN.
-
Enter the port used for the LAN port, for example
ge-0/0/3
. -
In the IP Address setting, enter
192.168.1.1
to assign the WAN edge device.1
for use as gateway in the network. -
Enter
/24
for the Prefix Length. - To provide DHCP services to endpoints on this network, select the button for DHCP server.
-
Give your DHCP server an address pool starting with
192.168.1.100
and ending with192.168.1.200
. -
Enter
192.168.1.1
as the Gateway to be assigned to DHCP clients. -
Finally, enter
1.1.1.1,8.8.8.8
as DNS Servers to be assigned to clients on the network. -
Click Add at the bottom of the Edit LAN
Configuration side panel.
Policy
Your template has WANs and LANs; now you need to tell the device how to use them to connect users to applications. This is done using Traffic Steering and Application Policies.
Steering Policy
- Scroll to the Traffic Steering section of the template, and select Add Traffic Steering.
- Name your steering policy, for example, `local-breakout`.
- Select Add Paths to give your steering policy a path to send traffic.
- Select WAN as the path type, and select your WAN interface. For apps that use the policy, this indicates you want them sent directly out of the local WAN interface.
-
Click the check in the upper right of the Add Path
box, and then click Add at the bottom of the
Add Traffic Steering side panel.
Application Policy
- Scroll to the Application Policy section of the template, and select Add Policy.
-
Enter a string in the name column, and click the check box to the right of
your entry.
- From the Network column drop-down, select your LAN network.
- From the Applications column drop-down, select your Internet app.
-
From the Traffic Steering column drop-down, select
your local breakout steering policy.
Assign to Site
- Scroll to the top and click Save.
-
Click the Assign to Site button, and select the site
where you want the template config applied.
Add the Device to the Site
At this point you have the following:
-
Your SSR device in your inventory.
-
A WAN edge template for configuration in Mist.
-
Your WAN edge template associated with your site in Mist.
Associating the device with the site and template gets you a working config!
Add the Device
- Go to your organization's WAN Edges Inventory.
- Select your device.
- Assign the device to your site.
- If you are configuring a Mist-managed router (SSR Software version 6.x and greater), check the Manage configuration with Mist check box. For version 5.4.x and greater conductor-managed routers, make sure there is no check mark in the Manage Configuration from Mist under Manage Configuration.
- Select Assign to Site.
Congratulations, you have a Mist-claimed SSR120, with a basic configuration ready to send to your device! Step 2 will get your SSR120 rack or wall mounted, connected to your network, and powered up.
