La implementación del protocolo Neighbor Discovery (ND) en la pila de IPv6 en Cisco IOS anterior a v15.0(1)XA5 permite a atacantes remotos provocar una denegación de servicio (consumo de CPU y bloqueo de dispositivo) mediante el envío de muchos mensajes Router Advertisement (AR) con distintas direcciones origen, como demostró el programa flood_router6 en el paquete thc-ipv6, también conocido como ID de error CSCti33534
