Course Description
Course Overview
This is week 1 of a two week course. This course is designed to provide students with MPLS-based virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS concepts such as control and forwarding plane, RSVP Traffic Engineering, LDP, Layer 3 VPNs, next-generation multicast virtual private networks (MVPNs), BGP Layer 2 VPNs, LDP Layer 2 Circuits, and virtual private LAN service (VPLS).
This course also covers JunOS operating system-specific implementations of Layer 2 control instances and active interface for VPLS. Through demonstration and hands-on labs, students will gain experience in configuring and monitoring JunOS routers running MPLS and VPN.
Course Objectives
