Junos MPLS Fundamentals (JMF)

DURATION
2 days

LEVEL
Basic

OBJECTIVES
This two-day course is designed to provide students with a solid foundation on Multiprotocol Label Switching (MPLS). After introducing concepts such as MPLS forwarding and the structure of the MPLS header, the course will delve 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 concepts are put into practice with a series of in-depth hands-on labs, which will allow participants to gain experience in configuring and monitoring MPLS on Junos OS devices.

PREREQUISITES
Students should have intermediate-level networking
knowledge and should be familiar with the Junos OS command-line interface (CLI). Students should also attend the Introduction to the Junos Operating System (IJOS), Junos Intermediate Routing (JIR), and Junos Service Provider Switching (JSPX) courses prior to attending this class.

WHO SHOULD ATTEND
This course benefits individuals responsible for configuring and monitoring devices running the Junos OS.
