For text strings separated by a pipeyou must specify either string1 or string2, but you cannot specify both or neither of them.
Multiprotocol Label Switching integrates jubos performance and confiyuration capabilities of data link Layer 2 with the scalability and flexibility More information. Then, what is MPLS? Comments in the configuration examples are shown either preceding the lines configuratin the comments apply to, configutation more often, on the same line.
If the order in which the LSPs are calculated is changed, the resulting set of physical paths for the LSPs also can change. Audience on page xx! Examples of command output are generally shown in a fixed-width font to preserve the column alignment. Part 1, Overview, provides an overview of Traffic Engineering concepts and configuration statements.! Options Describes the configuration statement s options if there are any. Flexible LSP Calculation and Configuration Traffic engineering involves mapping traffic flow onto a physical topology.
Components of Traffic Engineering on page 3! You can determine the paths online using constraint-based routing. The focus of the course is on VPN technology More information.
Junos MPLS Training & Documentation – Steve Puluka
Regardless of how the physical path is calculated, the forwarding state is installed across the network using RSVP. Start display at page:. August 2, Last Updated: For multiple options, if one option is the default, that fact is stated. Routing and Routing Protocols Provides an overview of routing concepts and describes how to configure routing, routing policy, and unicast routing protocols.! The remaining sections in the configuration guidelines are generally arranged so that the most common features are near the beginning.!
When the packet arrives at the egress applicationd, the label is removed and the packet exits the MPLS domain. Data Networking applicahions Architecture The course focuses on theoretical principles and practical implementation of selected Data Networking protocols and standards. Chapter 2 MPLS networks. In an actual configuration, comments can only precede a line; they cannot be on the same line as a configuration statement.
CSPF is a shortest-path-first algorithm that has been modified to take into account specific restrictions when calculating the shortest path across the network. The most famous applications More information.
Multiprotocol Label Switchingoriginating in IPv4, was initially proposed to improve forwarding speed. Internet Routing Ch Traffic engineering is composed of four functional components:! Questions Introduction Paresh Khatri paresh.
These chapters provide an overview of the configuration statement hierarchy for each software component.!
The new software built-in into the FMV, More information. For some statements, you can specify a set of values. This information is provided in the text of the statement summary. Label Pushing and Popping Figure After the offline calculation is completed, the LSPs can be established in any order because each is installed following the rules for the globally optimized solution.
Its core technology can be extended aapplications multiple network protocols, such as IPv6, Internet Packet More information.
Each applicatikns describes a major functional area of the JUNOS software, and the individual chapters within a part describe the software components of that functional area.
This chapter includes the following sections: A VPN is an extension of a private network that uses More information.
An explicit route is a preconfigured sequence of routers that should be part of the physical path of the LSP. In examples, text that you type literally is shown in a bold font.
JUNOS Internet Software Configuration Guide. Release 5.0. MPLS Applications. Juniper Networks, Inc.
Statement gulde command names that you type literally are shown in a nonitalicized font. Juniper Networks, More information. When you type the area statement, you substitute a value for area-id. The standard flooding algorithm used by the link-state IGPs ensures that link attributes are distributed to all routers in the routing domain.
An offline planning and analysis tool simultaneously examines each link configruation resource constraints and the requirements of each LSP. Physical network architecture is described More information. Chapter 10 JunOS Cookbook: The jumos, with a bold page number on the same line as the statement name, references the statement summary section. For options with numeric values, the allowed range and default value, if any, are listed.
This program and its documentation were developed at private expense, and no part of them is in the public domain. This process is repeated at each router in the LSP until configurationn packet reaches the egress router.
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.
To configure routing instances, include statements at the [routing-instances routing-instance-name mlls More information. Provide precise control over how traffic is rerouted when the primary path is faced with single or multiple failures.!
