The JNCIA-Junos Bundle is a two-day event that provides the foundational knowledge required to configure Juniper routing and switching products running Junos Software as well as prepare networking professionals with beginner-intermediate knowledge of networking in preparation for the JNCIS-Junos Certification.

JNCIA-Junos exam topics are based on the content of the recommended instructor led training courses:

  1. Introduction to the Junos Operating System (IJOS)
  2. Junos Routing Essentials (JRE)

This course provides the foundational knowledge required to configure Juniper routers running Junos Software. Key topics include user interface options with a heavy focus on the command-line interface (CLI), configuration tasks typically associated with the initial setup of devices, interface configuration basics and examples, secondary system configuration, and the basics of operational monitoring and maintenance of Junos devices. Students will also learn Juniper Networks routing fundamentals and how to configure basic connections, routing policy and firewall filters.

Course Duration: 2 days

Students should have basic networking knowledge and an understanding of the OSI model and the TCP/IP protocol suite.

Course Objectives:

After successfully completing this course, students should be able to:

  • Describe the basic design architecture of the Junos OS
  • Identify and provide a brief overview of Junos devices
  • Navigate within the Junos CLI
  • Perform tasks within the CLI operational and configuration modes
  • Restore a Junos device to its factory-default state
  • Perform initial configuration tasks
  • Configure and monitor network interfaces
  • Describe user configuration and authentication options
  • Perform secondary configuration tasks for features and services such as system logging (syslog) and tracing, Network Time Protocol (NTP), configuration archival and SNMP
  • Monitor basic operation for the Junos OS and devices
  • Identify and use network utilities
  • Upgrade the Junos OS
  • Perform file system maintenance and password recovery on a Junos device
  • Navigate within the Junos J-Web interface
  • Explain basic routing operations and concepts
  • View and describe routing and forwarding tables
  • Configure and monitor static routing
  • Configure and monitor OSPF
  • Describe the framework for routing policy
  • Explain the evaluation of routing policy
  • Identify instances where you might use routing policy
  • Write and apply a routing policy
  • Describe the framework for firewall filters
  • Explain the evaluation of firewall filters
  • Identify instances where you might use firewall filters
  • Write and apply a firewall filter
  • Describe the operation and configuration for unicast reverse path forwarding (RPF)
