crea una topologia de red para Mininet que tenga los siguientes aspectos: 1 controlador ryu 2 switches ovs conectados entre si y conectados al controlador 4 host para el s1 y 8 para el s2 3 Vlans, Vlan10 valn20 y vlan30 vlan 20 y 30 estaran en el s2 y vlan 10 en s1 ips para vlan 10 asigan a los host desde el rango 192.168.0.1 - 192.168.0.62/26 vlan 20 asignas 192.168.0.65 - 192.168.0.126 vlan 30 asignas del rango 192.168.0.129 - 192.168.0.190 y aparte genera un script para el controlador ryu que solo deje haya comunicacion entre los hosts que estan en las vlans 20 y 30 entre si, y que los hosts de la vlan 10 se comuniquen entre si pero no con el resto
**Topología de red en Mininet** Primero, debemos crear la topología de red en Mininet. Para ello, crearemos un archivo llamado `topologia.py` con el siguiente contenido: ```python from mininet.topo import Topo from mininet.net import Mininet from mininet.node import Switch, Host from mininet.link import Link, Intf from mininet.util import dumpNodeConnections class Topologia(Topo): def __init__(self): super(Topo, self).__init__() #
