Advanced Juniper Networks Routing (40hrs)
Course Overview
This lab-intensive, hands-on course provides an advanced look at popular routing and traffic engineering protocols supported on Juniper Networks M-series and T-series platforms. The AJNR course investigates the intricacies of interior gateway protocol (IGP) operation through OSPF and IS-IS labs that engage the student in a detailed examination of the link-state database and the effects of virtually all protocol options. The complexities of large-scale routing using BGP are then explored, with the focus placed on scaling networks using route reflection and confederations. In addition, numerous BGP options, such as multihop, multipath, and authentication, are discussed and configured in a lab setting. The class moves on to cover advanced JUNOS software features relating to MPLS and traffic engineering. In these sections the student is exposed to detailed discussions of RSVP and LDP signaling. Additional topics include CSPF and ERO-based routing constraints, routing table integration options, and traffic protection. The final sections of the course are devoted to a detailed exploration of multicast routing protocols, such as PIM, MSDP, and MP-BGP, in the context of interdomain multicast topologies that permit the demonstration of advanced multicast configuration options and monitoring.
Objectives
This is an intensive, hands-on, five-day course, with students participating in a variety of configuration and troubleshooting scenarios. Each student team controls its own router and participates in building large, multifunctional networks. Students who complete this course should be proficient in the configuration and operation of the major protocols and features supported in JUNOS software.
Intended Audience
The primary audience for this course includes personnel who are responsible for the provisioning, deployment, and troubleshooting of Juniper Networks router-based networks.
Course Level
This is an advanced-level course.
Prerequisites
Students should be able to configure, without assistance, a simple network using any of the following protocols: OSPF, IS-IS, BGP, RSVP, PIM. Student should have knowledge of the JUNOS Internet software configuration syntax to the extent covered in the Configuring Juniper Networks Routers course.

Advanced Policy (32hrs)
Course Overview
This course provides a detailed examination of the JUNOS software policy framework. The course begins with a quick review of policy basics and then quickly moves to advanced topics. It provides detailed discussions of load balancing, policy evaluation, and route creation. How routing policies affect the interior gateway protocols as well as multicast routing are examined. The complexities of implementing and using policies in relation to BGP are then explored. The discussion centers on the default behavior of the basic BGP attributes and their response to policy controls. Most course modules provide examples and use policies that are relevant in real-world networks. Students then implement those examples in the accompanying labs.
Objectives
This is an intensive, hands-on, four-day course, with students participating in a variety of configuration and troubleshooting scenarios.
