Course Description
Learn MPLS concepts as well as how to configure and monitor Junos OS while preparing for your JNCIS-SP certification.
In this course, you will learn about Multiprotocol Label Switching (MPLS) concepts such as control and forwarding plane, RSVP Traffic Engineering, LDP, Layer 3 VPNs, BGP Layer 2 VPNs, LDP Layer 2 Circuits, and virtual private LAN service (VPLS), carrier-of-carrier VPNs. This course also covers Junos operating system-specific implementations of Layer 2 control instances and active interface for VPLS and it is based on the Junos OS Release 12.3R2.5.
Through demonstrations and hands-on labs, you will gain experience in configuring and monitoring the Junos OS and in device operations.
Certification:
Juniper Networks Certified Internet Specialist (JNCIS-SP)
