This five-day course is designed to provide students with detailed coverage of OSPF, IS-IS, BGP, and routing policy. Through examples,
demonstrations, and hands-on labs, students will gain experience in configuring, monitoring, and troubleshooting the Junos operating system an
in monitoring device and protocol operations.

This course uses Juniper Networks vMX Series Routers for the hands-on component, but the lab environment does not preclude the course from
being applicable to other Juniper hardware platforms running Junos OS. This course is based on Junos OS Release 23.2.
