This five-day course is designed to provide students with detailed coverage of OSPF, ISIS, 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.The Advanced Junos Service Provider Routing (AJSPR) is an advanced-level course.Relevant Juniper Product• Junos OS • M Series • MX Series • PTX Series • T Series

TARGET AUDIENCE:
This course benefits individuals responsible for implementing, monitoring, and troubleshooting Layer 3 components of a service provider's network.
COURSE PREREQUISITES:
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.
