General Purpose
This tutorial is designed to equip networking professionals with the skills necessary to manage y optimize Internet access in environments with multiple service providers.
Through a series of practical and detailed tutorials, participants will learn how to implement advanced solutions that ensure the continuity of Internet service, improve network performance and reliability, and offer more efficient and personalized traffic management.
Objectives by Chapter
1. Configure Internet Output Routes with Failover
You will learn how to ensure a continuous Internet connection by configuring failover on edge routers connected to multiple providers.
This chapter covers from the initial configuration of interfaces and masking rules, to the implementation of exit routes with gateway availability check y metrics adjustment to prioritize suppliers.
2. Configure Internet exit routes with failover, redirecting traffic through a specific provider
This segment focuses on assigning specific routes to different clients in a failover environment, allowing users to ensure that certain clients always use a designated provider, despite general failover mechanisms.
Includes advanced settings route marking y routing tables for granular traffic management.
3. Configure recursive Internet egress routes with PCC Load Balancing
Students will learn to implement PCC load balancing with recursive routes to optimize the use of multiple Internet providers.
This chapter teaches how to ensure full route functionality to known points on the Internet, using concepts such as Scope y Target Scope, and how to test the configuration to ensure its effectiveness.
What the student will obtain at the end of this course
Upon completion of this course, participants will have acquired practical and theoretical skills essential for configuring and managing networks in environments with multiple Internet providers. They will be able to:
- Implement failover solutions to ensure an uninterrupted connection to the Internet.
- Effectively configure PCC load balancing and recursive routes to optimize network performance.
- Perform advanced management of network traffic, assigning specific routes to specific clients and ensuring service continuity even in the event of provider failures.
- Diagnose and resolve problems related to route configuration and network performance.
This tutorial offers IT professionals the tools and knowledge necessary to significantly improve the resilience, efficiency and customization of the networks they manage, preparing them to meet the challenges of an increasingly complex and demanding network environment.
