MPLS Applications - Part two

Length: Five days
Cost: Please contact us


A student following the MPLS Applications Part II should be familiar with operational and configuration modes in the Juniper Networks JUNOS operating system, as well as able to configure and troubleshoot IGP routing protocols, BGP as well as have a fundamental understanding of IP Multicast. It is recommended that students have followed or are familiar with the concepts covered in MPLS Applications Part I including LDP and RSVP configuration options such a P2MP LSPs prior to following this course.

Course Overview

This course focuses primarily on the design and deployment of MPLS VPNs. Both Layer-3 and Layer-2 VPNs are discussed and compared. Every module is accompanied with a hands-on lab to reinforce the concepts learned in the theory. As in the Part I, the course is designed to provide students with the necessary skills to know how to configure and troubleshoot various MPLS VPNs, as well as the application of the many features supported by MPLS VPN technologies.
