Advanced Junos Enterprise Routing

Overview

The 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, Border Gateway Protocol (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

Pre-Requisites

The knowledge and skills that a learner must have before attending this course are as follows:

•  Basic networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also have working experience with basic routing principles.

To gain the prerequisite skills and knowledge,Juniper strongly recommends the knowledge of the following courses:

•     Junos Operating System (IJOS)
•     Junos Routing Essentials (JRE)
•     Junos Intermediate Routing (JIR)
