[lacnog] Consulta sobre cisco

(Soy Carlos, no Alejandro :-) )

Me funcionó *casi* bien, con dos observaciones:

- no lo pude hacer funcionar para IPv6
- el timeout cuando una interfaz se baja es un poco largo, como 30 s 
(los timeouts x defecto de spanning tree)

Seguramente se pueda mejorar, cabe notar que estoy probando con un IOS 
bastante viejo (12.algo)

Te adjunto la configuración.
