Junos MPLS Fundamentals (JMF)
This two-day course aims to give students a firm grounding in Multiprotocol Label Switching (MPLS). The course will delve into the configuration and operation of the two primary label distribution protocols, RSVP and LDP, after introducing ideas such as MPLS forwarding and the structure of the MPLS header. The key concepts of traffic engineering and MPLS traffic protection, such as fast rerouting, link/node protection, and LDP loop-free alternate, are highlighted in particular. Participants get hands-on experience configuring and monitoring MPLS on Junos OS devices as part of a series of in-depth hands-on labs that put the concepts into practice. These practical labs make use of vMX Series devices from Juniper Networks running the Junos OS Release 19.2R1.8 and are also applicable to other MX Series devices.
Duration: 2 Days (16 Hours)
Learning Objectives:
- Explain the history & rationale for MPLS and its basic terminology.
- Explain the MPLS label operations (push, pop, swap) & the concept of the label-switched path (LSP).

- Explain the functionalities & operation of RSVP & LDP.
- Configure & verify RSVP-signaled & LDP-signaled LSPs.
- Select & configure the appropriate label distribution protocol for a given requirement.
- Explain the default Junos OS MPLS traffic engineering behavior.
- Explain the Interior Gateway Protocol (IGP) extensions used to build the Traffic Engineering Database (TED).
- Explain the Constrained Shortest Path First (CSPF) algorithm, its uses, & its path selection process.
- Explain administrative groups & how they can be used to influence path selection.
- Explain the default traffic protection behavior of RSVP-signaled LSPs.
- Explain the use of primary & secondary LSPs.

Q: What is enterprise switching?
A: This means the enterprise network has a great core switch, with additional distribution layer switches which generally operate below it to bring all the information into the data center & after that, disseminate it out to the access layer where the end users are located & there is fewer data traffic.
Q: Is a router the switch?
A: A switch connects several devices to create a network, and a router connects multiple switches, & their respective networks to form an even more extensive network. These networks may be in various locations or across multiple sites.
Q: What is Juno's Operating System?
A: Juniper Networks provides high-performance network devices that create a responsive & trusted environment for accelerating the deployment of services & applications over a single network. The Junos operating system (Junos OS) is the foundation of these high-performance networks.
Q: What is the infrastructure required to attend your training program?
A: To attend the training session, you should have operational Desktops or Laptops with the required specification and a good internet connection to access the labs.
Q: What if I miss a class on a particular day?
A: We would always recommend you attend the live session to practice & clarify the doubts instantly & get more value from your investment. However, due to some contingency, if you have to skip the class, Radiant Techlearning will help you with the recorded session of that particular day. However, those recorded sessions are not meant only for personal consumption & NOT for distribution or commercial use.
Q: How will I be accessing the labs?
A: Radiant Techlearning has a data center containing the Virtual Training environment for participant hand-on-practice.
Participants can easily access these labs over Cloud with the help of a remote desktop connection.
Radiant virtual labs allow you to learn from anywhere in the world & in any time zone.
Q: What kind of projects are included as a part of training?
A: The learners will be enthralled as we engage them the real-world & industry Oriented projects during the training program. These projects will improve your skills & knowledge & you will gain a better experience. These real-time projects will help you a lot in your future tasks & assignments.
