==Summary==


VXLAN (Virtual Extensible LAN) encapsulates Layer 2 Ethernet frames within Layer 3 packets, creating a Layer 2 network over a Layer 3 infrastructure. It acts as a virtual switch, interconnecting routers and all devices connected to them into an extended Layer 2 network, enhancing scalability and flexibility. In this article several methods to configure a '''VXLAN tunnel''' between '''two Teltonika devices''' will be demonstrated.

==VXLAN over Mobile network==
 
[[File:Vxlan mobile wan topology.png|border|class=tlt-border|1100px]]
In this section, VXLAN will be set up between two Teltonika devices using Mobile WAN, requiring two public IPs—one for each RUT device. The configuration steps will be similar to those described in the [[#VXLAN over Wired WAN|VXLAN over Wired WAN]] section of this page, except for the '''APN''' settings and the '''Network > Devices''' section settings, where the remote address of the created VXLAN interface will be updated to reflect the other router's public IP.
 
===Configuring APN settings===
----
 
First, both RUT1 and RUT2 devices must have '''Public IP''' addresses. To achieve this, manually assign the relevant APN settings to their mobile interfaces to obtain Public IPs:

==VXLAN over VPN tunnel==
 
[[File:Vxlan vpn topology.png|border|class=tlt-border|1100px]]
If only one Public IP address is available, VXLAN can be configured through a VPN tunnel. In this case, an IPsec VPN will be used, where RUT1 acts as the VPN server and RUT2 as the client. The VPN creates remote tunnel endpoints, which can then be integrated into the VXLAN configuration to enable Layer 2 communication between the routers.
 
The configuration steps will be similar to those outlined in the [[#VXLAN over Wired WAN|VXLAN over Wired WAN]] section of this page, with the addition of '''IPsec configuration''' and adjustments in the '''Network > Devices''' settings, where the remote address of the created VXLAN interface will be updated to correspond to the VPN tunnel endpoint of the other router.

==Configuration testing==
The best way to test the configuration after setting up VXLAN between the routers is to ping between devices on either side of the routers using their LAN IPs and check the ARP tables. This ensures that devices on the same LAN segment can communicate over the Layer 2 (L2) network through the routers.
 
Configuration testing from RUT1 side:
 
[[File:Vxlan ping rut1 to rut2.png|border|class=tlt-border]]
 
If the MAC address for the specified IP address in the ARP table matches the RUT2's MAC address, it confirms that the configuration is functioning correctly.

VXLAN support has been introduced starting with firmware version 00.07.09 and later. It is advised to update to the latest firmware available.

The information in this page is updated in accordance with 00.07.09.1 firmware version.

Summary

VXLAN (Virtual Extensible LAN) encapsulates Layer 2 Ethernet frames within Layer 3 packets, creating a Layer 2 network over a Layer 3 infrastructure. It acts as a virtual switch, interconnecting routers and all devices connected to them into an extended Layer 2 network, enhancing scalability and flexibility. In this configuration example, three methods to configure a VXLAN tunnel between two Teltonika devices will be demonstrated.

Prerequisites

  • Two routers with installed VXLAN packages, will refer to these as RUT1 and RUT2
  • End device like Laptop or Mobile Phone
  • Two Public IP addresses for configuring VXLAN over the Mobile network
  • One Public IP address for configuring VXLAN over the VPN tunnel


VXLAN package Installation

First, install the VXLAN package on both RUT1 and RUT2 devices. This package is available on firmware version 07.09 and later, therefore, updating the router's firmware is a mandatory step if it is outdated. After the update, the package can be found in the Package Manager in the WebUI.

Navigate to System > Package Manager

  1. In the search bar look for vxlan packet
  2. Click Install

Configuration of VXLAN over Wired WAN

In this section, the setup of VXLAN over Wired WAN using RUT1 and RUT2 devices will be described. The process will show how to create a VXLAN tunnel to connect the devices and allow them to communicate over the wired network.

Configuring the Wired WAN Interfaces

The same steps will be followed to configure the WAN interfaces on RUT1 and RUT2, which will be on the same subnet but with different IP addresses, enabling layer 3 communication between them.

RUT1 WAN configuration

Navigate to the Network > WAN section in the WebUI, then click the Edit button for the wired WAN interface.

Configuration window will open. Adjust following:
  1. Ensure interface is Enabled
  2. Change Protocol to Static
  3. Enter Ipv4 address for communication in this Wired WAN network
  4. Select your preferable IPv4 netmask
  5. Click Save & Apply twice

RUT2 WAN configuration

Navigate to the Network > WAN section in the WebUI, then click the Edit button for the wired WAN interface.

Configuration window will open. Adjust following:

  1. Ensure interface is Enabled
  2. Change Protocol to Static
  3. Enter Ipv4 address for communication in this Wired WAN network
  4. Select your preferable IPv4 netmask
  5. Click Save & Apply twice
