Análisis de la Practica 5.5.3 Problemas del Protocolo Spanning Tree

En esta práctica se identifica el estado inicial de todos los enlaces troncales, además de corregir el origen del problema, y la configuración del switch.
Esta práctica se completa cuando todos los enlaces trúncales cableados llevan tráfico y los switches participan en el balanceo de carga por VLAN para las 3 VLAN deusuario.
Se realiza la configuración básica del switch, tomando en cuenta que los puertos realizan reenvíos en cada switch e identificar que enlaces troncales no se van a utilizar en la configuración predeterminada.
En cada switch se realiza el comando show run y arroja la siguiente información:
Switch1 | Switch2 | Switch3 |
