Document Organization

This manual is divided into several parts. Each part describes a major functional area of the JUNOS software, and the individual chapters within a part describe the software commands of that functional area.

This manual contains the following parts and chapters:

• Preface, About This Manual (this chapter), provides a brief description of the contents and organization of this manual and describes how to contact customer support.
• Part 1, "Overview," provides an overview of traffic engineering concepts and configuration statements.

• Chapter 1, "Traffic Engineering Overview," provides a functional description of the four major components of traffic engineering, as well as the various methods of calculating and configuring label-switched paths (LSPs).
• Chapter 2, "Complete MPLS Applications Configuration Mode Statements," provides a comprehensive list of all the configuration statements available and displays their hierarchy.

• Part 2, "MPLS," describes how to configure the JUNOS software to support Multiprotocol Label Switching.

• Chapter 3, "MPLS Overview," provides a short overview of MPLS, which provides a mechanism for engineering network traffic patterns that is independent of the shortest path determined by a routing protocol.
• Chapter 4, "MPLS Configuration Statements," lists all minimum and optional configuration statements for MPLS.
• Chapter 5, "Configure MPLS-Signaled LSPs," describes how to configure the ingress router for signaled Label Switched Paths (LSPs) and how to enable RSVP.
• Chapter 6, "Configure Static LSPs," describes how to configure the ingress, intermediate, and egress routers for static MPLS.
• Chapter 7, "Configure Explicit-Path LSPs," describes how to manually configure LSPs by specifying each router hop between the ingress and egress routers.
• Chapter 8, "Configure Miscellaneous MPLS Properties," describes how to configure MPLS to gather statistics and trace protocol packets and operations, as well as how to control syslog messages and Simple Network Management Protocol (SNMP) traps.
• Chapter 9, "Summary of MPLS Configuration Statements," lists all the statements used to configure MPLS.

• Part 3, "RSVP," describes how to configure the JUNOS software to support the Resource Reservation Protocol.

• Chapter 10, "RSVP Overview," provides a short overview of RSVP, a setup protocol designed to interact with integrated services on the Internet to request a specific quality of service (QoS).
• Chapter 11, "RSVP Configuration Guidelines," describes the minimum and optional configurations for RSVP.
• Chapter 12, "Summary of RSVP Configuration Statements," describes all RSVP configuration statements.

• Part 4, "LDP," describes how to configure the JUNOS software to support Label Distribution Protocol (LDP).

• Chapter 13, "LDP Overview," provides a short overview of LDP, a protocol used to establish LSPs through a network by mapping network-layer routing information directly to data-link label-switched paths.
• Chapter 14, "Configure LDP," describes the minimum and optional configurations for LDP.
• Chapter 15, "Summary of LDP Configuration Statements," describes all LDP configuration statements.

• Part 5, "CCC and TCC," describes how to configure the JUNOS software to support circuit cross-connect (CCC).

• Chapter 16, "CCC and TCC Overview," describes the types of CCCs.
• Chapter 17, "CCC and TCC Configuration," describes how to configure CCC configuration statements.
• Chapter 18, "Summary of CCC Configuration Statements," describes all CCC configuration statements.

• Part 6, "GMPLS," describes how to configure the JUNOS software to support Generalized Multiprotocol Label Switching (GMPLS).

• Chapter 19, "GMPLS Overview," describes GMPLS.
• Chapter 20, "GMPLS Configuration," describes how to configure GMPLS configuration statements.
• Chapter 21, "Summary of GMPLS Configuration Statements," describes all GMPLS configuration statements.

This manual also contains a glossary, a complete index, and an index of statements and commands.
