Aperçu du cours

Overview

In this lab, you will be working with a service provider’s MPLS network that includes several routers configured across different Autonomous Systems (AS). The main objective is to establish and manage multi-tenant environments using advanced BGP/MPLS VPN technologies. This setup will help you understand and implement the separation and management of overlapping IP spaces between different customer sites using Virtual Routing and Forwarding (VRF) instances, MPLS, and MP-BGP.

Objectives

• Configure and troubleshoot a multi-tenant network using MPLS and BGP.
• Implement VRF to manage overlapping IP addresses for different customers securely and efficiently.
• Utilize MP-BGP to extend routing information between customer sites across the service provider’s backbone.

Scenario

You are part of a network engineering team at a service provider managing an MPLS network that connects two remote customer sites. Each site has two customers with overlapping IP address spaces:

• Customer A and Customer B at both Site 1 and Site 2.
• Both sites use the IP prefix  192.168.1.0/24  for Site 1 and  192.168.2.0/24  for Site 2.

Your task is to configure the network to ensure private and secure communication between each customer’s sites without interference between the customers, despite the overlapping IP spaces.

Prerequisites

• Solid understanding of MPLS and BGP fundamentals.
• Familiarity with Cisco IOS commands and configuration.
• Basic knowledge of network security practices and VRF concepts.
