This three-day course provides students with the foundational knowledge required to work with the Juniper Networks Junos operating system and to configure Junos devices. The course provides a brief overview of the Junos device families and discusses the key architectural components of the 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 with configuration examples, secondary system configuration, and the basics of operational monitoring and maintenance of Junos devices.

The course then delves into foundational routing knowledge and configuration examples including general routing concepts, routing policy, and firewall filters.

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

  • Describe the basic design architecture of the Juniper Networks 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 and firewall filters.
  • Explain the evaluation of routing policy and firewall filters.
  • Identify instances where you might use routing policy.
  • Write and apply a routing policy.
  • 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).
