In this JUNOS JNCIA training course, you will find all the videos required to understand, operate and maintain Juniper JUNOS devices. You will find in this course of more than 50 videos detailed information regarding how JUNOS works and operate, together with the required configuration and verification process and protocol knowledge to be able to pass the JNCIA JN0-101 certification exam.

The JNCIA is the fundamental Juniper certifications and its required to move further into more advanced certification like the JNCIS.

This course is structured into 4 major categories:

- JUNOS FUNDAMENTALS
- JUNOS ROUTING
- JUNOS FIREWALL FILTERS
- JUNOS COS

At the end of this course, you will be able to work fluently on Juniper JUNOS devices, pass the JNCIA certification and move forward into more advanced certifications like the JNCIS

JUNIPER JUNOS FUNDAMENTALS - JNCIA

JUNOS fundamentals for the JNCIA Certification JN0-101 exam.

  • JUNIPER JUNOS - ARCHITECTURE FUNDAMENTALS (10:23)

    In this video we present an introduction to the architecture of the JUNOS software. We also provide an overview about the hardware components in a typical Juniper box, like the Routing Engine and the Packet Forwarding Engine, its functions and how traffic is processed on each of the components

  • JUNIPER JUNOS - CLI MODES (09:56)

    In this video we will see what are the differences between accessing a Juniper device as the admin user (root) and as a regular user. Additionally, we will see the different modes that are available in the JUNOS command line.

  • JUNIPER JUNOS - GENERAL CLI INTERACTION (15:22)

    In this video you will see the different ways we can interact with the JunOS command line, specifically how we can get direct help in the CLI and improve our speed.

  • JUNIPER JUNOS - CONFIGURATION LEVELS (14:41)

    This video will show some fundamental concepts to be able to navigate the JUNOS configuration. We will also present a brief introduction to the "set" and "insert" commands

  • JUNIPER JUNOS - CONFIGURATION MODEL (11:32)

    In this video we will explore the Juniper JunOS configuration model. We will see the differences of the JUNOS configuration compared with most of the others manufacturers and what advantages JunOS has.

  • JUNIPER JUNOS - DELETE DEACTIVATE AND OTHER RELATED COMMANDS (11:52)

    This video will continue to explore operators of the JUNOS command line, in this case the delete, deactivate, rename, replace, copy and annotate commands.

  • JUNIPER JUNOS - CONFIGURATION MANAGEMENT (07:41)

    Introduction to the operation of the JUNOS configurations and basic commands for verification.

  • JUNIPER JUNOS - COMMIT MANAGEMENT (14:28)

    In this video we explore how to apply a candidate configuration to the running configuration of a JUNOS device and the different parameters that can be used while performing this task. We will also see other related commands to manipulate the system configuration like load / save.

  • JUNIPER JUNOS - JWEB (11:01)

    Installation and overview of the alternative to the command line for Juniper JUNOS devices, the JWEB interface.

  • JUNIPER JUNOS - FIRST CONFIGURATION STEPS (11:21)

    In this video we talk about the minimum configuration requirements for a Juniper device. We will also see the procedure to remove the configuration of a device and how to return it to the "factory default".

  • JUNIPER JUNOS - INITIAL CONFIGURATION (09:27)

    What do we have to do, to get a Juniper Junos device up and running? Using the command line we will see in this video how to do a basic setup, and to deploy a configuration to remotely manage our juniper device.

  • JUNIPER JUNOS - RESCUE CONFIGURATION (10:48)

    In this video we talk about another interesting feature in JUNOS, the rescue configuration. We answer questions like: Why is useful? How can we create it? How can we delete it?

  • JUNIPER JUNOS - INTERFACE TYPES (05:54)

    A key part in managing JUNOS is to understand the different types of interfaces that exist on a device running JUNOS. In this video we explore each of them and their respective roles.

  • JUNIPER JUNOS - INTERFACE NAMING AND CHARACTERISTICS (11:09)

    Each interface in JUNOS follows a specific naming, with a unique meaning, in this video we describe this concepts together with the description of the properties each interfaces may have.

  • JUNIPER JUNOS - INTERFACE CONFIGURATION (08:23)

    In this video we show a few typical configuration examples of various interfaces types and their respective properties (physical and logical).

  • JUNIPER JUNOS - USER AUTHENTICATION (10:32)

    We explore the different authentication methods that exist within JUNOS, the internal authorization mechanisms and pre-set templates in the operating system to restrict user capabilities.

  • JUNIPER JUNOS - SYSLOG AND TRACING (20:53)

    Overview of the syslog and trace options facilities in JUNOS. We present in this video how to handle the syslog service and how to work with trace options, a useful tool when a deeper troubleshooting is required.

  • JUNIPER JUNOS - TIME AND NTP CONFIGURATION (09:00)

    The need for our network devices to remain with their clocks synchronized is critical to ensure that all systems logs are consistent (very helpful in troubleshooting). In this video we discuss the ways that exist in JUNOS to change the system clock, including NTP.

  • JUNIPER JUNOS - CONFIGURATION BACKUP AND ARCHIVAL (08:05)

    Having a backup configuration in a central server is essential for a quick recovery. JUNOS has a built-in feature that allows you to fulfil this role; in this video we explore this option and its corresponding configuration.

  • JUNIPER JUNOS - BASIC SNMP CONFIGURATION (11:25)

    SNMP is widely used to monitor the status of network devices such as servers, routers and switches. In this video we will show you how to perform a basic SNMP configuration in JUNOS.

  • JUNIPER JUNOS - DEVICE AND INTERFACE STATUS (11:49)

    It is critical for any network administrator to be able to quickly determine what is the status of a network device or any of it's components (The power supply, a module or an interface). In this video we will present the various commands available in JUNOS to fulfil these tasks..

  • JUNIPER JUNOS - BASIC TROUBLESHOOTING TOOLS (17:39)

    From our devices we can test the network connectivity using standard basic tools. In this video we will see the various commands available in JUNOS to fulfil these tasks.

  • JUNIPER JUNOS - INTRODUCTION TO COS (09:15)

    Quality of service is found in most of today's networks, especially when multiple not necessarily equal services operate on a common network. In this video we explain how Juniper understand and implement QOS.

  • JUNIPER JUNOS - FORWARDING CLASSES AND LOSS PRIORITY (08:04)

    The concept of quality of service typically consists of several components that perform the tasks of classification, marking, queuing, scheduling, policing and shaping. In this video we go into the details behind the concept of Forwarding Classes / Loss Priority

  • JUNIPER JUNOS - BEHAVIOUR AGGREGATE CLASSIFICATION (13:40)

    To classify the traffic that comes into a JUNOS device, you have two options. In this video we will discuss the option of Behaviour Aggregate, where basically we use the bits allocated inside the fields of QoS on L2/L3 headers

  • JUNIPER JUNOS - MULTIFIELD CLASSIFICATION (07:52)

    To classify the traffic that comes into JUNOS device, you have two options. In this video we will discuss the Multi-field classifier, using general attributes of the traffic (origin, destination, information L4/L7) to do our classification.

  • JUNIPER JUNOS - SCHEDULING (08:03)

    In this video we will discuss a high level overview of the "scheduling" model that Juniper JUNOS implements and its relationship with physical queues. We will also see what the "scheduling" job is in the general QoS model of Juniper.
