6 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.
