Each entry in the forwarding table contains an interface-inbound label pair mapped to a set of forwarding information that is applied to all packets arriving on the specific interface with the same inbound label. To configure a stub area, include the stub statement at the [edit protocols ospf area area-id] hierarchy level.! This manual also contains a glossary, a complete index, and an index of statements and uunos. Also, let us know if you find any mistakes in the documentation.

A VPN is an extension of a private network that uses. How Routers Forward Packets Autumn philip. Traffic engineering provides the capabilities to:! The old label is replaced with a new label, and the packet is forwarded to the next hop along the LSP.

You should consult the license for further details. An LSP is created by the concatenation of one or more label-switched hops, allowing a packet to be forwarded from one router to another across the MPLS domain. February 27, The feature detects when a neighbor is down and quickly triggers a state timeout, which More information.

Support for strict and loose explicit routes allows the path selection process to be given broad latitude whenever possible, but to be constrained when necessary. This chapter includes the following sections: Data Networking and Architecture.

Configutation standard flooding algorithm used by the link-state IGPs ensures that link attributes are distributed to all routers in the routing domain. When you type the area statement, you substitute a value for area-id. Copyright,,The Regents of the University of California. This product includes memory allocation software developed by Mark Moraes, copyright,University of Toronto. Once the packet begins to traverse the LSP, each router uses the label to make the forwarding decision.

This process is repeated at each router in the LSP until the packet reaches the egress router. This document or any part thereof may not More information.

Syntax Describes the full syntax of the configuration statement. Description Describes the function of the configuration statement.!

The information distribution component is implemented by defining relatively simple extensions to the IGPs so that link attributes are included as part of each router s link-state advertisement.

Components of Traffic Engineering! If the order in which the Mpla are calculated is changed, the resulting set of physical paths for the LSPs also can change.

A separate database is maintained so that the subsequent traffic engineering computation is independent of the IGP and the IGP s link-state database.

MPLS Configuration Overview

The packet is then forwarded based on the destination IP address contained in the packet s original IP header according to the traditional shortest path calculated by the IP routing protocol. Recall that the explicit route can be either strict or loose.!

This program and its documentation were developed at private expense, and no part of them is in the public domain. Then, what is MPLS? Statements, commands, filenames, directory names, IP addresses, and configuration hierarchy levels are shown in a sans serif font. Configuration statements Lists all the configuration statements available to configure the software component.

Using the Indexes on page xxiv! The labeled packet is forwarded along the LSP by each router until it reaches the tail end of the LSP, at which point the MPLS header is removed and the packet is forwarded based on Layer 3 information such as the IP destination address.
