    vDay One: mastering JUnOs COnfigUratiOn

    this vDay One book is all about Junos and the magic behind the curly brackets. Log onto Junosphere, load the topology file, watch the books videos, and then sim-ply copy and paste from the PDf books prompts to configure the Junosphere virtual machine online. Learn by doing, not reading.

    Junosphere provides a cost-effective and flexible environment where you can create and run networks in the cloud. these net-works can be used for the same exercises you perform today in your physical lab and more, including network design, modeling, troubleshooting, testing, and training.

    Virtual Day One - Learn by Doing! n experience the Junos CLi in both videos and

    real hands-on training modules

    n Learn how to navigate through the Junos


    n master basic and advanced configuration


    n Unveil the mysteries of rollback and commit


    n Understand how Junos handles simultaneous

  • Juniper networks Junosphere cloud-based services allow networking professionals to perform network testing, design, and training exercises in a risk-free virtual environment that uses real network operating systems. Junosphere allows you to closely replicate physical networks consisting of Junos Os-based devices

    and ecosystem tools without the cost, complexity, or limitations of a physical lab.

    to ensure you have the best possible experience with Junosphere, check that you have the required settings.

    Consider these recommendations for optional freeware programs to facilitate Junosphere usage.



    n Only firefox 19 and higher, and internet explorer 9 and higher, are supported

    n enable pop-ups for junosphere.net

    n allow downloads from junosphere.net

    n install latest Java plug-in



    n RealVNC - Remote access to the CentOS server

    n PuTTY - ssH/telnet client to access device consoles

    n Notepad++ - reader of configuration files

    n FileZilla - ftP client to access device consoles

    n 7zip - Creates compressed topology filesets

    n VmWare Player - to run the connector

    Client Hardware Recommendations

    CPU: 1 gHz or higher is recommended for Windows; for mac, 1 gHz g4 or intel processor is recommended.

    memory: minimum of 256 mB of available ram is recommended.

    Color quality: for best results, use 16-bit (8-bit, 24-bit, and 32-bit are also supported).

    monitor resolutions: 1,024 x 768 pixels is recommended; up to 2,048 x 2,048 pixels is supported.

    I would like to first thank my wife Eva, and my sons Manuel and Lucas, for their love and patience despite all the extra hours I dedicated to this project. Patrick Ames for his endless positive energy and creativity. Dave Dugal for the voice narration and his ability to make me smile. Aleksey Mints for the very timely and collaborative integration of vDay One in my favorite (by far) network lab environment: Junosphere. Julie Wider for the kind help organizing the beta testing and for promoting the program inside the J-Net Community. Diogo Montagner for the technical review and for his involvement in vDay One. Pilar Somohano and Pablo Mosteiro for their honest support and global vision. Levent Ogut for the commit history tip. My father for the effort he always puts in to make complex things look simple: I wish I learned it from him!

    Special thanks to the beta testers who went through the material and provided feedback. All of them are from the Juniper Ambassador Team: Kevin Barker, Martin Brown, Nick Ryce, Steve Puluka and Victor Gonzalez. Pilar Somohano and Aleksey Mints provided useful feedback on the Junosphere setup video. Finally, I would also like to acknowledge all my customers and colleagues in Juniper Networks in Spain, who promoted this material and did the alpha testing of the proto-type, especially: David Soriano (Telefonica), Rubn Daz (Acuntia), Alfredo Pelaez (NSN), Jose Maroto (Tecnocom), Daniel Toro, Rocio Benavente, Miguel Angel Rodriguez a.k.a.

    Welcome to vDay One

    This vDay One book provides a virtual hands-on workshop with the following components:

    Videos: Each chapter contains a link to a YouTube video explaining the methodology or the relevant concepts in detail.

    A Real Junos OS Device: The single-device topology used in this workshop is ready for you to start and it is in the Public Library of Junosphere. The term device refers to a router, or a switch, or a firewall, etc. In this case, the device is a VJX, but the principles of Junos OS configuration that you learn here apply to all the physical and virtual platforms.

    This Book: In order to keep you focused on the practi-cal tasks, this book simply contains a step-by-step lab procedure, together with the links to videos describing each lab practice.

    This vDay One book covers the most important aspects of Junos Configuration. It targets readers who are either new to Junos OS CLI or who want to improve their configuration skills. The techniques covered range from very basic configura-tion to relatively advanced administration techniques. With the toolbox covered in this book, you will boost your mastery of the Junos OS configuration database.


    The 3h00m of net time needed to go through the material on Junosphere is an estimate. It is suggested that you book more time to take breaks, though, as you may be curious enough to check out other commands, or you may need to spend addi-tional time if you are new to Junos OS or to Junosphere. The current reservation model in Junosphere works on a per-day basis, so its flexible in that sense.

    The prerequisites for this virtual workshop are:

    A valid Junosphere account (http://www.junosphere.net). To order Junosphere with a special discount, go to https://learningportal.juniper.net/juniper/user_ac-tivity_info.aspx?id=5735 and enter promo code jun3928 , valid for Junosphere CLASSROOM only (not for LAB).

    You need to have administration rights on your computer to install the Network Connect software. Note that although installation typically works fine in the first attempt, some users had to retry once or twice, and finally got it working.

    It is not possible to run two simultaneous instances of Network Connect, so if you are already have a Network Connect instance running for a corporate VPN, you will need to stop that first.

    Network Connect works best without web proxies, and it works fine with static proxy configuration as well. However, it doesnt work if the browser is configured with a PAC (Proxy Auto-Configuration) file.

    IMPORTANT The beginning of this book (you can see the back cover page) lists the web browser, system and application recommendations for Junosphere. Save yourself time and read through the browser, system, and application requirements.

    TIP If youll be cutting and pasting commands and con-figuration blocks directly from this PDF into the terminal, tests have shown using Acrobat Reader works better than other apps with PDF capabilities these other apps can run lines of code together.
