CCNA Gratis 2026 – Guía Práctica STP en Cisco Packet Tracer con 3 switches

CCNA2025 STP Lab – Step-by-Step Configuration in PacketTracer In this free video from the Learn Networks from Scratch course, we continue with the key topic of Spanning Tree Protocol (STP) within the CCNA and CCNP Enterprise certification series. I'll show you a practical lab in Cisco PacketTracer using three switches: SW1, SW2, and SW3. The goal is to designate SW1 as the Root Bridge for VLAN 10 and SW2 as the Root Bridge for VLAN 20, while correctly configuring the ports, verifying the STP topology, and ensuring that VLAN 10 uses a different primary route than VLAN 20. You'll see: the process of choosing the BridgeID, priority settings, identifying root and blocked ports, how STP works in a specific VLAN (in this case, 10 and 20), and how convergence behaves in a three-switch redundant environment. This lab prepares you for the CCNA 200-301/v1.1 exam and gives you hands-on experience with the Packet Tracer simulator. If you're interested in learning about networking, mastering Layer 2 protocols, and preparing for the CCNA or CCNP certification, this video is for you.
