Configuring Juniper Networks Routers

The course is an intermediate-level, instructor-led course that focuses on the configuration of system and protocol-related features for the Juniper Networks M-series and T-series platforms , as well as operation and troubleshooting of Juniper Networks Routers. This class is a combination of lecture and lab to allow ample time for hands-on exposure to the JUNOS software configuration-mode and operational-mode analysis of protocol operation. This course exposes attendees to fault-analysis procedures and troubleshooting techniques to enable rapid problem determination and resolution.
The primary audiences for this course include network operations and engineering support staff, including personnel who are unfamiliar with Juniper Networks Router configuration, Internet engineers, and Network Operations Center engineers.
Objectives
After successfully completing this course, you will be able to:
. Perform initial configuration on M-series and T-series platforms.
. Describe the basic functionality of the RIP routing protocol and how to configure it on a Juniper Networks M-series or T-series platform.
. Use the routing policy within JUNOS software to control routes within the routing and forwarding tables.
. Describe the basic functionality of the OSPF routing protocol and how to configure it on a Juniper Networks M-series or T-series platform.
. Describe the basic functionality of the IS-IS routing protocol and how to configure it on a Juniper Networks M-series or T-series platform.
. Describe the basic functionality of the BGP routing protocol and how to configure it on a Juniper Networks M-series or T-series platform.
. Describe the concept of traffic engineering and how to configure MPLS on a Juniper Networks M-series or T-series platform.
. Describe how packet filtering can control the flow of IP packets and provide security within the Juniper Networks M-series and T-series platforms.
. Configure and monitor IP multicasting on a Juniper Networks M-series or T-series platform.
Course Level
This is an intermediate-level course designed to provide an in-depth exposure to general configuration and routing protocol operation to prepare students for the more advanced Juniper Router courses available.
Prerequisites
· A basic familiarity with the JUNOS software CLI;
· TCP/IP basics;
· Link-state routing protocols, including a familiarity with either OSPF or IS-IS;
