En algunos entornos, puede ser necesario agrupar varios links seriales para actuar como un único link con ancho de banda agregado. Este documento describe cómo configurar routers Cisco 4500 para agrupar cuatro interfaces seriales mediante una plantilla de interfaz de plantilla virtual.
Esta configuración puede utilizarse para los routers conectados sobre líneas arrendadas o routers que tienen la Unidad de servicio de canales/Unidad de servicio de datos (CSU/DSU). Puede agregar funciones adicionales a esta configuración en función de sus necesidades.
No hay requisitos específicos para este documento.
La información que contiene este documento se basa en las versiones de software y hardware indicadas a continuación.
Routers Cisco 4500 en un entorno de laboratorio con configuraciones despejadas.
Cisco IOS® versión 12.2(10b) se estaba ejecutando en ambos routers.
La información que se presenta en este documento se originó a partir de dispositivos dentro de un ambiente de laboratorio específico. All of the devices used in this document started with a cleared (default) configuration. Si la red está funcionando, asegúrese de haber comprendido el impacto que puede tener un comando antes de ejecutarlo.
Esta configuración también puede ser usada con las siguientes versiones de hardware y software.
Dos routers cualesquiera con cuatro interfaces seriales cada uno.
Se pueden utilizar las interfaces seriales WIC-1T y WIC-2T.
Para obtener más información sobre las convenciones del documento, consulte Convenciones de Consejos Técnicos de Cisco.
En esta sección encontrará la información para configurar las funciones descritas en este documento.
Nota: Para encontrar información adicional sobre los comandos usados en este documento, utilice la Command Lookup Tool (sólo clientes registrados) .
Este documento utiliza la instalación de red que se muestra en el siguiente diagrama.
Esta configuración fue probada utilizando la versión 12.2(10b) del software Cisco IOS en routers de la serie 4500. Los mismos conceptos de configuración se aplican a una topología de router similar u otras versiones de Cisco IOS.
Este documento usa las configuraciones detalladas a continuación.

Configure lo siguiente para implementar la configuración anterior:
plantilla virtual multilink
interface virtual-template
Multilink PPP en cada una de las interfaces seriales en las que debe realizarse el agrupamiento.
Un RIP como protocolo de ruteo IP
El loopback 0 de la interfaz se configura para que nunca falle, y ip unnumbered loopback 0 mejora el agrupamiento de más de cinco interfaces seriales con la misma dirección IP.
Cuando todas las interfaces seriales están activas y se envía tráfico de usuario, el PPP de links múltiples crea una interfaz de acceso virtual y se lleva a cabo la negociación PPP. La configuración para esta interfaz de acceso virtual está clonada de la plantilla virtual. La cantidad de interfaces seriales que están activas se agrupan en esta interfaz de acceso virtual y se crea un ancho de banda adicional.
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.
