Junos Enterprise Switching Using Enhanced Layer 2 Software (JEX)

Introduction to Junos switching concepts and operation.

GK# 7209 Vendor# JEX

Course Overview


This two-day course provides students with intermediate routing knowledge and configuration examples. The course includes an overview of protocol independent routing features, load balancing and filter-based forwarding, OSPF, BGP, IP tunneling, and high-availability (HA) features.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and monitoring device operations. This course uses Juniper Networks SRX Series Services Gateways for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS.
