Advanced Junos Service Provider Routing (AJSPR)

Advanced Junos Service Provider Routing (AJSPR) 

This five-day course is designed to provide students with detailed coverage of OSPF, IS-IS, BGP, and routing policy. Through demonstrations and hands-on labs, students will gain experience in configuring, monitoring, and troubleshooting the Junos operating system and in monitoring device and protocol operations. This course uses Juniper Networks vMX Series Routers 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 19.3.

Course Level

Advanced Junos Service Provider Routing (AJSPR) is an advanced-level course.

Intended Audience

This course benefits individuals responsible for implementing, monitoring, and troubleshooting Layer 3 components of a service provider’s network.


Students should have intermediate-level networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also attend the Introduction to the Junos Operating System (IJOS) and Junos Intermediate Routing (JIR) courses prior to attending this class.


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

  • Describe the various OSPF link-state advertisement (LSA) types.
  • Explain the flooding of LSAs in an OSPF network.
