Junos Layer 3 VPNs (JL3V) Course Overview

Junos Layer 3 VPNs (JL3V) Course Overview

The Junos Layer 3 VPNs (JL3V) course offers an in-depth study of MPLS-based Layer 3 Virtual Private Networks (VPNs) on Juniper Networks devices. It begins with an introduction to MPLS VPNs, including the basics and provider-provisioned VPN structures. Learners will then delve into the specific terminology, address structures, and operational characteristics of Layer 3 VPNs.

Subsequent chapters guide students through basic configuration, scaling, and advanced options such as Class of Service (CoS) and integration with GRE and IPsec tunneling. The course also covers hierarchical and interprovider backbones, critical for understanding complex VPN models.

Troubleshooting skills are honed in Chapter 8, ensuring participants can navigate through potential issues effectively. The course concludes by exploring multicast VPNs, including Draft Rosen and Next-Generation multicast VPNs, with comprehensive lessons on configuration and monitoring.

Designed for networking professionals, this course enhances skills in deploying and managing Junos-based VPNs, increasing network reliability and service quality for end-users.

This is a Rare Course and it can be take up to 3 weeks to arrange the training.
