Junos Layer 3 VPNs Training Course Overview

In this comprehensive three-day course, students will acquire in-depth knowledge and practical configuration skills for MPLS-based Layer 3 VPNs (L3VPN). The curriculum covers essential MPLS L3VPN concepts, addressing topics such as scaling L3VPNs, Internet access, interprovider L3VPNs, and multicast for L3VPNs. Specific focus is given to Junos operating system (OS) implementations of Layer 3 VPNs, with hands-on labs designed to provide participants with practical experience in configuring and monitoring L3VPNs on Junos OS devices. Utilizing Juniper Networks vMX Series devices running Junos OS Release 22.1R1.10, these labs are equally applicable to other MX Series devices, ensuring a robust and versatile learning experience.
