This five-day 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, 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. This course is based on the Junos OS Release 12.3R2.5.
Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and in device operations.Currently no training dates
