Configuración Cisco 877 Ip dinámica

[atn87]

Hola buenas. Les cuento mi duda:

Tengo un router Cisco serie 870 (modelo 877). Necesito saber si alguien puede ayudarme con la configuración para salir a Internet. Tiene 4 interfaces FastEthernet y una interfaz Atm0.

La IP suministrada por el ISP es dinámica. Si alguien sabe o tiene alguna plantilla de configuración similar le agradecería su ayuda.

Un saludo.

Para telefonica. Pero sirve para cualquier operador solo se tiene que cambiar las direcciones ip del interfaz ethernet y los vpi/vci, correspondientes.

interface FastEthernet0
ip address 175.90.90.90 255.255.255.128 secondary
ip address 172.16.0.254 255.255.255.0 secondary
ip address 172.16.8.254 255.255.255.0
ip nat inside

interface ATM0

Una cosilla, la FastEthernet que has puesto al principio de la configuración qué IPs tengo yo que poner??? Es que, por lo que he leido el 877 trata los puertos FastEthernet como un switch por lo que no tiene IPs. ¿Por qué tu si le das IP?

Yo no puedo darle IP, me sale un mensaje de no sé qué de "L2 links"...

Yo tambien tengo problemas para poder poner en funcionamiento un Cisco con ADSL ip dinamica con telefonica.

¿Alguien que pilote de CISCO puede pegarle un vistazo?

Graciasss
