Este documento proporciona una configuración de ejemplo para la devolución de llamada PPP entre dos routers Cisco.
No hay requisitos específicos para este documento.
La información que contiene este documento se basa en las siguientes versiones de software y hardware.
Cisco IOS® Software Release 12.0(3)T o posterior.
Nota: Para configurar la devolución de llamada PPP con la ayuda de una cadena de devolución de llamada asignada a un servidor AAA, debe utilizar el comando dialer aaa, que está disponible en la versión 12.0(3)T o posterior del software del IOS de Cisco. Sin embargo, en Cisco IOS versiones 12.1(4)T, 12.2(1)T y posteriores, este comando no es necesario para la devolución de llamada PPP con una cadena de devolución de llamada asignada a un servidor AAA.
Nota: El comando dialer aaa sólo se soporta con DDR heredado (como se muestra en la figura 1).
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

El TACACS+ (servidor AAA) se utiliza para proporcionar la cadena de marcado de devolución de llamada al servidor de devolución de llamada. Sin embargo, también puede utilizar RADIUS para suministrar la cadena de devolución de llamada. Para configurar la devolución de llamada PPP con autenticación, autorización y contabilidad (AAA) local, vea Configuración de la devolución de llamada PPP sobre ISDN.
En esta configuración de ejemplo, la devolución de llamada utiliza PPP y las instalaciones especificadas en RFC 1570. La devolución de llamada PPP a través del circuito ISDN se completa en este orden:
El cliente de devolución de llamada inicia y activa una conexión ISDN al router del servidor de devolución de llamada.
El cliente de devolución de llamada y el servidor de devolución de llamada negocian el protocolo de control de enlaces PPP (LCP). En la negociación LCP, se solicita, negocia y acuerda la devolución de llamada.
El cliente de devolución de llamada y el servidor de devolución de llamada se autentican entre sí con el protocolo de autenticación de contraseña PPP (PAP) o el protocolo de autenticación por desafío mutuo (CHAP). Sin embargo, puede configurar el cliente de devolución de llamada para que no autentique el servidor de devolución de llamada, a través del comando ppp authentication chap callin.
El servidor de devolución de llamada obtiene los atributos de devolución de llamada necesarios, como la cadena de marcado de devolución de llamada (el número de teléfono del cliente) del servidor AAA.
Ambos routers descartan la conexión ISDN.
El servidor de devolución de llamada inicia la devolución de llamada al cliente. Cuando la llamada se conecta, los routers se autentican mutuamente y se establece el link.

Configuración gratuita de TACACS+ |

user = tremens { default service = permit login = cleartext "cisco" chap = cleartext "cisco" !--- CHAP password. service = ppp protocol = lcp { callback-dialstring = "6083" !--- Number to callback. send-secret = "cisco" } } |
También puede utilizar RADIUS como servidor AAA para suministrar los atributos de devolución de llamada en lugar de TACACS+. Aquí se proporciona un ejemplo de la configuración RADIUS:
Configuración RADIUS |
---|
tremens Auth-Type = Local, Password = "cisco" Service-Type = Framed-User, !--- Service-Type(6) is Framed User(4). Cisco-AVPair = "lcp:callback-dialstring=6083", Cisco-AVPair = "lcp:send-secret=cisco" |
Nota: En la configuración RADIUS que se muestra arriba, se necesita Cisco AVPair lcp:send-secret=cisco en el momento de la autenticación de la devolución de llamada. Si no incluye este AVPair, debe configurar el nombre de usuario CHAP y la contraseña del router remoto localmente en el servidor de devolución de llamada.
Nota: Este documento trata principalmente de TACACS+. Las depuraciones proporcionadas en este documento no muestran una devolución de llamada iniciada por RADIUS.
Nota: Desde la versión 12.1(7) del IOS de Cisco, es posible utilizar el atributo RADIUS 19 del Grupo de Trabajo de Ingeniería de Internet (IETF) para la devolución de llamadas de ISDN y Microsoft analógica. En tal caso, no es necesario utilizar Cisco AVPaires, como se muestra en la configuración anterior. Consulte el ejemplo de configuración RADIUS alternativa que se muestra aquí:
Configuración RADIUS alternativa |
---|
tremens Auth-Type = Local, Password = "cisco" Service-Type = callback framed !--- Service-Type (6) is callback framed (4). !--- Callback framed is also known as !--- Dialback-Framed-User. Callback =6083 !--- IETF RADIUS Callback attribute (19) with the phone !--- number for the callback. |
Nota: Las depuraciones RADIUS mostrarán el atributo RADIUS 19 de IETF devuelto al servidor de devolución de llamada.

En esta sección encontrará información que puede utilizar para confirmar que su configuración esté funcionando correctamente.
La herramienta Output Interpreter (sólo para clientes registrados) permite utilizar algunos comandos “show” y ver un análisis del resultado de estos comandos.
show dialer interface type number : muestra información de diagnóstico general para las interfaces configuradas para el ruteo de marcado a pedido (DDR). Las direcciones de origen y destino del paquete que inició el marcado se ven en la línea de motivo del marcado. Este comando también muestra los temporizadores de conexión.
show isdn status: permite asegurarse de que el router se comunica correctamente con el switch ISDN. Verifique en el resultado que el estado de la capa 1 sea ACTIVE (Activo) y que aparezca MULTIPLE_FRAME_ESTABLISHED en la capa 2. Este comando muestra también el número de llamadas activas.

Nota: Antes de ejecutar un comando debug, consulte Información Importante sobre Comandos Debug.
debug isdn q931: muestra la configuración de la llamada y el desmontaje de la conexión de red ISDN (Capa 3).

debug ppp negotiation: muestra información sobre el tráfico PPP y los intercambios mientras la negociación de los componentes PPP está en curso, incluidos el protocolo de control de enlaces (LCP), la autenticación y NCP. Una negociación PPP exitosa abrirá primero el estado LCP, luego realizará la autenticación y por último negociará el NCP.
debug ppp authentication: muestra los mensajes del protocolo de autenticación PPP, incluidos los intercambios de paquetes del protocolo de autenticación por desafío mutuo (CHAP) y los intercambios del protocolo de autenticación por contraseña (PAP). Si observa una falla, verifique si el nombre de usuario y la contraseña CHAP están configurados correctamente.
debug callback: muestra los eventos de devolución de llamada cuando el router utiliza un módem y un script de chat para devolver la llamada en una línea de terminal. Como este comando es para módems y scripts de chat, no se utiliza en esta configuración.
