Description

Introduction

Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs) provide secure, scalable, and efficient communication for enterprises and service providers. By leveraging MPLS technology, businesses can create isolated networks for different customers while maintaining high performance and Quality of Service (QoS). This course covers the fundamental concepts, implementation techniques, and best practices for configuring MPLS VPNs.

Prerequisites

• Understanding of basic networking concepts (IP addressing, subnetting, and routing).
• Familiarity with MPLS fundamentals and label switching.
• Knowledge of routing protocols such as BGP, OSPF, or IS-IS.
• Basic experience with network configuration on Cisco or Juniper devices.
