OmniSwitch AOS Release 6 Network Configuration Guide

Multiprotocol Label Switching (MPLS) is a label switching technology that provides the ability to set up 
connection-oriented paths over a connectionless IP network. MPLS sets up a specific path for a sequence 
of packets. The packets are identified by a label inserted into each packet.

This implementation of MPLS provides the network architecture that is needed to set up a Virtual Private 
LAN Service (VPLS). VPLS allows multiple customer sites to transparently connect through a single 
bridging domain over an IP/MPLS-based network.

The MPLS architecture provided is based on the Label Distribution Protocol (LDP). The LDP consists of a 
set of procedures used by participating Label Switching Routers (LSRs) to define Label Switched Paths 
(LSPs), also referred to as MPLS tunnels. These tunnels provide the foundation necessary to provision 
VPLS.

This chapter documents the OmniSwitch implementation of an LDP-based MPLS network architecture. 
For information about how to configure VPLS, see 

This chapter describes the basic components of MPLS and how to configure them through the Command 
Line Interface (CLI). CLI commands are used in the configuration examples; for more details about the 
syntax of commands, see the Omniswitch CLI Reference Guide.
