Layer 2 Point to Point Network with Edge Pro or Edge Lite

Layer 2 Point to Point Network with Edge Pro or Edge Lite


Introduction: Use this Configuration Guide to set up Layer 2 Point-to-Point Network (Shared LAN)

Use this Configuration Guide to setup a Layer 2 Point to Point SD-WAN Network using Big Network. Big Network SD-WAN enables Layer 2 connectivity features not commonly found in competing SD-WAN solutions.

Design Diagram / Application Concept


This configuration guide will set up a cloud network using a layer 2 point-to-point connection to extend an existing network (right side of the diagram) to a remote location (left side of diagram).


The existing LAN has an IP range of 192.168.100.0/24 with the Default Gateway of 192.168.100.1. Servers, Remote Desktop Nodes, and the CRM are all numbered using DHCP from 192.168.100.10 to 192.168.100.150.


The goal is for Big Network to create a Layer 2 point-to-point connection to securely extend an existing network to a second, remote location (shown on the left).


Required Hardware

Use Big Network Edge Pro or Edge Lites to create your Layer 2 Point to Point SD-WAN Cloud Network.

Step #1: On-Board your Edge Device

  • Please Follow the guide below to onboard your edge device

Step #2: Define a Cloud Network

Your next step is to create a “Cloud Network”. A Cloud Network is a collection of devices that share a common Layer 2 network. Just think of it as your virtual LAN in the cloud.  Devices joined to a Cloud Network have complete access to each other. Communication between Edge Pro and Edge Lite devices via a Cloud Network is completely secured using AES-256 bit encryption. 


Navigate to Cloud Networks

  • Click on “Create Network”; a wizard will appear to collect details about your Cloud Network.

  • Provide a Name and Description for your Cloud Network

  • Click “Next”

  • Define an IP Address Pool - Since this is an L2 network there is no need to define the IP pool just select “Do not assign address pool”.

  • Click “Next”

  • Define access to the Cloud Network - You may leave this blank since we only want Edge devices to join the network.

  • Click “Next”.

  • Now finalize

    • To proceed, click “Create”

    • To proceed, click “Network”

With a Cloud Network defined, we next need to connect our Edge Pro or Edge Lites - proceed to Step #3.

Step #3: Bridge Cloud Network to Location #1 Edge Pro or Edge Lite

Connecting physical ports on your Edge Device to Cloud Networks creates the final “gateway” connection needed to extend your physical network to a Cloud Network. 


  • Navigate to “Edge Devices”

  • Select “Configure” next to the Edge Pro / Lite you want to use.

  • Select “Networks” to see configured Networks on the device.

  • Select “Edit Config”

  • Select “Create Local Network”

    • Provide the Network a Name.

    • Click “Confirm”

  • Expand the newly created network; select “Connection”

  • In “Connected Cloud Network” select the Cloud Network you defined in Step #2.

  • In “Connected LAN Interfaces” select the physical ports you wish to use with your existing network.

  • Click “Validate” to validate the configuration.

  • Click the “Pending Changes” gear to review configuration changes.

  • Click “Apply” to Apply the configuration changes.

  • Click “Back”.

  • Click “Config History” to observe the configuration being applied to Edge Devices. When the new configuration’s checkbox turns from Blue to Green, you know the new configuration is applied.

  • Perform the same steps for the second (remote) Edge device.

Step #4: Repeat Step #3 for Location #2 Edge Pro or Edge Lite


In this step, repeat the items from Step #3 for your second Edge Pro or Edge Lite.

Step #5: Let’s test it out!

Deploy your Edge Pro and Edge Lites to their respective locations. 


Once you have setup your Edge Pro or Edge Lites in this fashion, you can now access resources available across the Cloud Network as though you were on the same Local Area Network (LAN). For example, if you had a web server running at 192.168.100.10 at Location #1, you should be able to access your server from a laptop at Location #2, despite them being on different routed Internet connections.
