Junos MPLS Fundamentals (JMF) Certification Training Course Overview

This course is structured to provide participants with a concrete foundation on Multiprotocol Label Switching (MPLS). After getting introduction on the concepts such as MPLS forwarding and the structure of the MPLS header, the course will go into the configuration and operation of the two main label distribution protocols, RSVP and LDP. Special emphasis is given to the central topics of traffic engineering and MPLS traffic protection, including fast reroute, link/node protection, and LDP loop-free alternate. The lab session will utilize Juniper Networks vMX Series devices using the Junos OS Release 19.2R1.8, and it is also applicable to other MX Series devices.


  • Anyone who is responsible for configuring and monitoring devices running the Junos OS
