Advanced Policy
Course No: EDU-JUN-POL
Length: Four days
Cost: $2,700 (US) Schedule and Registration
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. Each student team controls its own router and participates in building large, multifunctional networks. Students that complete this course should be proficient in controlling the dissemination of routing information and route modification 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 M-series and T-series router-based networks.
Course Level
This is an advanced-level course.
Prerequisites
Students should be able to configure basic RIP, OSPF, IS-IS, and BGP networks without assistance. Students should have knowledge of the JUNOS Internet software policy syntax to the extent covered in the Configuring Juniper Networks Routers course.
