El diseño del Hot Standby Routing Protocol (HSRP), tal como se implementa en Cisco IOS 12.1, cuando se utiliza IRPAS, permite a atacantes remotos provocar una denegación de servicio (consumo de CPU) mediante un router con la misma dirección IP que la interfaz en la que se ejecuta HSRP, lo que provoca un bucle.
