Advanced Junos Service Provider Routing
AJSPR Training

Overview

This 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.

Duration 5 days.

You can find current trainings on training calendar page.

Training Prerequisites

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