Junos Layer 3 VPNs

Course information
Price: Please Call
Day(s): 3
Course Code: JL3V
GTC: 23

Overview

This three-day course is designed to provide students with MPLS-based Layer 3 virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS Layer 3 VPN concepts, scaling Layer 3 VPNs, Internet access, Interprovider L3VPNs, and Multicast for Layer 3 VPNs. This course also covers Junos operating system-specific implementations of Layer 3 VPNs. This course is based on the Junos OS Release 15.1R2.9.


Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and in device operations. JL3V is an advanced-level course.

 

Pre-Requisites

Students should have intermediate-level networking knowledge and an understanding of OSPF, ISIS, BGP, and Junos policy. Students should have experience configuring MPLS label-switched paths using Junos. Students should also attend the Introduction to the Junos Operating System (IJOS), Junos Routing Essentials (JRE),  Junos Intermediate Routing (JIR) and the Junos MPLS Fundamentals (JMF) courses prior to attending this class.
