Configuração e gerenciamento de uma infraestrutura de redes: um estudo de caso

Abstract

This article presents the design, implementation, and validation of a simulated multi-site network topology for the fictional company ACUPENET, modeled using the Cisco Packet Tracer simulator. The core technical challenge lies in ensuring continuous and resilient connectivity among five geographically distributed branches in the face of potential communication link failures. To address this, the solution employs hierarchical addressing via Variable Length Subnet Masking (VLSM), dynamic routing using the RIP version 2 protocol, and serial link redundancy. Analysis of the results—conducted through the verification of routing tables and connectivity tests (ping)—demonstrates the topology's robustness and the correct propagation of routes between sites. The theoretical framework draws upon Kurose and Ross (2021) and Tanenbaum (2021) as classic references in the field. The study concludes that the proposed solution serves as an effective pedagogical tool for teaching distributed corporate networks.
