What the student will learn
By completing this tutorial, students will learn about:
- BGP Fundamentals
- BGP Session Configuration
- Subdivision of Routing Prefixes and Filters
- Redundancy Implementation with BGP Path Prepend
- IPv4 Prefix Announcement
- Multiple Supplier Management
- Diagnosis and Verification of BGP Ads

Requirements
- Understand basic networking concepts, such as network types (LAN, WAN), network topologies, and OSI/TCP-IP models.
- Know the differences between public and private IP addresses, and how they are used in networks.
- Have knowledge of subnets, netmasks and IP addressing.
- Understand the basic concepts of routing and switching in networks.
- Know how Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) work.
- Understand the assignment of dynamic and static IPs.
General Purpose
This tutorial (BGP as a routing protocol to advertise IPv4 resources to the Internet) Its general objective is to teach students how to implement the Border Gateway Protocol (BGP) to efficiently advertise IPv4 resources over the Internet.
The material covers everything from basic BGP configuration with a single provider to advanced implementation with multiple providers and the application of redundancy techniques to ensure service continuity in the event of possible failures.
Objectives by Chapter
1. BGP Implementation with a Provider
- Objective: Configure a BGP session to advertise IPv4 prefixes to a single Internet provider.
- Student Outcomes: Learn how to configure a BGP border router, establish a BGP session with a provider, and verify the correct publication of IPv4 prefixes.
2. BGP Implementation with Two Providers
- Objective: Expand BGP configuration to advertise IPv4 resources using two Internet providers, improving redundancy and routing efficiency.
- Student Outcomes: Understand how to subdivide IPv4 prefixes and configure separate BGP sessions for each provider, apply appropriate routing filters, and manage outbound routing.
3. BGP PATH PREPEND implementation
- Objective: Implement BGP Path Prepend filters to create redundancy in IPv4 resource publications, allowing traffic to be diverted to another provider in case of failure.
- Student Outcomes: Master the modification of the AS path through BGP Path Prepend to influence the selection of routes in the global network, ensuring the availability and resilience of the Internet connection.
What the Student Will Get at the End of the Tutorial
By the end of this tutorial, students will have acquired crucial skills in configuring and managing BGP for publishing IPv4 resources to the Internet. Specifically, students will be able to:
- Set up BGP sessions with one or more Internet providers.
- Advertise IPv4 prefixes across different providers to improve redundancy and routing efficiency.
- Implement redundancy techniques such as BGP Path Prepend to ensure service continuity in the event of provider failures.
- Manipulate the AS path to influence the routing decision at a global level, allowing finer control over egress traffic.
- Diagnose and verify the correct publication of IPv4 prefixes and the effectiveness of redundancy configurations.
This skill set will allow students to design and implement robust and resilient routing strategies for networks that require high availability and reliability in their Internet connection.
