Configuracion de Cisco 878 para acceso ADSL de Telefonica

Por si le es util a alguien, aqui les pego la configuracion basica de un router cisco 878, configurado para reemplazar el router adsl que normalmente entrega telefonica.
La configuracion de adsl es un tema que viene en los examenes para obtener la certificacion CCNP(en el ISCW), asi que me e divertido bastante aprendiendo a hacerlo con la documentacion, google y prueba y error.
