The primary pedagogical benefit of these exercises is forced troubleshooting under pressure. When a student configures HSRP with preemption and tracking, but the failover takes ten seconds instead of three, they must analyze debug standby outputs, check timers ( hello and hold intervals), and verify interface tracking. This mimics real-world conditions where a misconfigured standby priority can cause split-brain scenarios. Packet Tracer’s simulation mode allows step-by-step packet inspection, turning a frustrating error into a learning opportunity. Consequently, students move from memorizing commands to understanding state machines and packet flow.
Simula que el Router 1 pierde energía a los 2 minutos. El tráfico debe seguir fluyendo.
Configura dos routers para que compartan una misma IP virtual. Si el router principal falla, el secundario toma el control sin que los usuarios noten el corte.
2. Nivel Intermedio: Segmentación con VLANs y Enrutamiento Inter-VLAN (Router-on-a-Stick)
