Exploration: enrutamiento evaluación basada en aptitudes de EIGRP (Versión para el instructor)
Objetivos de aprendizaje Al completar esta práctica de laboratorio, usted podrá:
• Dividir en subredes un espacio de dirección en base a determinados requisitos. • Asignar direcciones adecuadas a interfaces y documentarlas en la tabla de direcciónes anterior. • Cablear la red según el diagrama. • Eliminar la configuración de inicio y recargar un router al estado por defecto. • Configurar el enrutamiento EIGRP en todos los routers. • Configurar y propagar una ruta estática por defecto. • Verificar el funcionamiento de EIGRP. • Probar y verificar la conectividad total. • Reflexionar sobre la implementación de la red y documentarlo.

Tarea 1: Creación de un esquema de direccionamiento.
Paso 1: Utilice la dirección 192.168.157.0/22 para crear un esquema de direccionamiento que incluya a todos los hosts de la red.
Documente todas las direcciones de subred en la Tabla 1: Nota para el instructor: Las subredes pueden variar según la forma en que el estudiante asigne cada subred. Las máscaras de subred deberían reflejar la cantidad de hosts por subred. Tabla 1
