1.- Permitir solo las vlan 1,10,20 en las interfaces Trunk
2.- Interfaz que conecta a Core 1 cambiar a GigabitEthernet
2.- Eliminar las Vlans y direcciones IPs.
3.- Gig0/0 no shut
3.- En el router R1-NV implementar Router On A Stick (ROAS), trunking encapsulation dot1Q
4.- Comprobar conectividad
Escenario actual:
