MPLS Model User Guide

Multi-Protocol Label Switching (MPLS) is a multi-layer switching technology that
uses labels to determine how packets are forwarded through a network. The
first part of this document describes key features of the MPLS specialized model
and the second part focuses on procedures for configuring MPLS in your
network model.

Model Features

This section contains a list of the main features available in the Multi-Protocol
Label Switching model:

•

The MPLS model captures the following protocol behavior:

Table 6-1 MPLS Model Features

Feature

Description

LSP (Label Switched Path) configuration

• LSPs can be created manually or

automatically from traffic conversation
pairs.

• LSPs are easily reused in other scenarios

or projects by using the LSP import and
export features.

• Both dynamic and static LSPs are created

using the path object.

Differential Services (DiffServ)

• DiffServ extensions, as defined in

RFC-2475, are provided.

• The model enables you to perform QoS

(quality of service) analyses by accounting
for different types of service.

Traffic Engineering

Traffic engineered routes are computed
using Constrained Shortest Path First
(CSPF) with OSPF or IS-IS routing protocols.
