Advanced Junos Enterprise Routing (AJER) Training Course


Advanced Junos Enterprise Routing (AJER) Certification Training Course Overview

Advanced Junos Enterprise Routing (AJER) course is designed to provide students with the tools required for implementing, monitoring, and troubleshooting Layer 3 components in an enterprise network. Detailed coverage of OSPF, BGP, class of service (CoS), and multicast is strongly emphasized. Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos operating system and in monitoring device and protocol operations. This course uses Juniper Networks SRX Series Services Gateways for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS. This course is based on the Junos OS Release 12.1X46-D20.5.

Audience: This course benefits individuals responsible for configuring and monitoring devices running the Junos OS.

  • Describe the shortest-path-first (SPF) algorithm, OSPF area types and operations.
  • Configure various OSPF area types.
  • Summarize and restrict routes.
  • Identify scenarios that require routing policy or specific configuration options.
  • Use routing policy and specific configuration options to implement solutions for various scenarios.
  • Describe basic BGP operation and common BGP attributes.
  • Explain the route selection process for BGP.
  • Describe how to alter the route selection process.
  • Configure some advanced options for BGP peers.
  • Describe various BGP attributes in detail and explain the operation of those attributes.
  • Manipulate BGP attributes using routing policy.
  • Describe common routing policies used in the enterprise environment.
  • Explain how attribute modifications affect routing decisions.
  • Implement a routing policy for inbound and outbound traffic using BGP.
  • Identify environments that might require a modified CoS implementation.
  • Describe the various CoS components and their respective functions.
  • Explain the CoS processing along with CoS defaults on SRX Series Services Gateways.
  • Describe situations when some CoS features are used in the enterprise.
  • Implement some CoS features in an enterprise environment.
  • Describe IP multicast traffic flow.
  • Identify the components of IP multicast.
