Basic Information
2.1L2TP Pseudowire
In networking, a pseudowire (PW) refers to a mechanism that allows the
encapsulation and forwarding of one type of network traffic over another type
of network. L2TP pseudowire specifically refers to the use of L2TP (Layer 2
Tunneling Protocol) to establish a virtual connection between two endpoints
over an IP or MPLS (Multiprotocol Label Switching) network, emulating the
behavior of a point-to-point or multipoint Layer 2 circuit.
L2TP pseudowire is often used in service provider networks to provide Layer 2
connectivity between geographically dispersed customer sites. It enables the
transport of Ethernet, Frame Relay, or ATM (Asynchronous Transfer Mode) frames
over an IP or MPLS network. The use of L2TP pseudowires allows service
providers to offer Layer 2 VPN services to their customers without the need
for dedicated physical circuits between customer sites.
In summary, L2TP pseudowire is a technique that utilizes L2TP to create
virtual Layer 2 connections over IP or MPLS networks, providing a flexible and
cost-effective way to extend Layer 2 networks across different locations.
Router App Description
3.1Web Interface
After Router App installation, the module’s GUI can be invoked by clicking the
router app name on the Router Apps page of router’s web interface.
Left part of this GUI contains menu with Status menu section, Configuration
menu section and Customization menu section. Customization menu section
contains only the Return item, which switches back from the module’s web page
to the router’s web configuration pages. The main menu of router app GUI is
shown on Figure below. 3.2L2TP
Configuration menu section contains L2TP item where all the setting of this
router app takes place.

System log section contains log messages.
Example
You have 2 devices between which you want to create L2TP pseudowire. Each
device have to have this router app installed and Config filled to reflect
settings of other device.
After that, the L2TP tunnel is created, which
can be confirmed by pinging other device
