Ejemplo: Uso de la política de enrutamiento en una red de ISP
Este ejemplo es un caso práctico de cómo se pueden usar las directivas de enrutamiento en una red típica de proveedor de servicios Internet (ISP).
Requisitos
No se necesita ninguna configuración especial más allá de la inicialización del dispositivo antes de configurar este ejemplo.
Descripción general
En este ejemplo de red, el número de AS del ISP es 64510. El ISP tiene dos pares de tránsito (AS 64514 y AS 64515) a los que se conecta en un punto de intercambio. El ISP también está conectado a dos pares privados (AS 64513 y AS 64516) con los que intercambia rutas específicas de clientes. El ISP tiene dos clientes (AS 64511 y AS 64512).
Las directivas de ISP se configuran en dirección saliente. Es decir, el ejemplo se centra en las rutas que el ISP anuncia a sus pares y clientes, e incluye lo siguiente:
Al ISP se le ha asignado el AS 64510 y el espacio de enrutamiento es 172.16.32.0/21. Con la excepción de las dos redes de clientes, todas las demás rutas de clientes se simulan con rutas estáticas.
Los pares de intercambio se utilizan para el servicio de tránsito a otras partes de Internet. Esto significa que el ISP está aceptando todas las rutas (la tabla de enrutamiento de Internet completa) de esos pares BGP. Para ayudar a mantener una tabla de enrutamiento de Internet optimizada, el ISP está configurado para anunciar solo dos rutas agregadas a los pares de tránsito.
Los administradores del ISP quieren que todos los datos de los pares privados utilicen los enlaces directos. Como resultado, todas las rutas de clientes del ISP se anuncian a esos pares privados. Estos pares luego anuncian todas las rutas de sus clientes al ISP.
Finalmente, cada cliente tiene un conjunto diferente de requisitos. El cliente-1 requiere una ruta predeterminada única. El cliente-2 requiere rutas específicas.
Establecer comandos para todos los dispositivos de la topología
Configuración rápida de CLI
Para configurar rápidamente este ejemplo, copie los siguientes comandos, péguelos en un archivo de texto, elimine los saltos de línea, cambie los detalles necesarios para que coincidan con su configuración de red y, a continuación, copie y pegue los comandos en la CLI en el nivel de jerarquía.[edit]

El dispositivo Customer-2 tiene dos rutas estáticas configuradas para simular las rutas del cliente. Estas rutas se envían al ISP. El cliente 2 tiene un vínculo con el ISP, así como un vínculo con el AS 8000. Este cliente ha solicitado al ISP rutas del cliente específicas, así como del AS 64516. El cliente 2 desea usar el ISP para el servicio de tránsito a Internet y ha solicitado una ruta predeterminada al ISP.

Configuración de los dispositivos ISP-1 e ISP-2
Procedimiento
Procedimiento paso a paso
El ejemplo siguiente requiere que navegue por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte el Manual del usuario de la CLI de Junos OS.Usar el editor de CLI en el modo de configuraciónhttps://www.juniper.net/documentation/en_US/junos/information-products/pathway-pages/junos-cli/junos-cli.html
El dispositivo ISP-1 y el dispositivo ISP-2 tienen configuradas dos directivas: La política y la política.private-peerexchange-peer Debido a sus configuraciones similares, este ejemplo muestra la configuración paso a paso solo para el dispositivo ISP-2.
En el dispositivo ISP-2, la política del par privado envía las rutas del cliente del ISP al par privado del dispositivo 2. La política acepta todas las rutas estáticas locales (clientes ISP-2 de dispositivos locales) y todas las rutas BGP en el rango 172.16.32.0/21 (anunciadas por otros enrutadores ISP). Estos dos términos de política representan las rutas del cliente del ISP. El término de directiva final rechaza todas las demás rutas, lo que incluye toda la tabla de enrutamiento de Internet enviada por los pares de intercambio. No es necesario enviar estas rutas al dispositivo Private-Peer-2 por dos motivos:
El par ya mantiene una conexión con Device Exchange-2 en nuestro ejemplo, por lo que las rutas son redundantes.
El par privado solo quiere rutas de clientes. La política logra este objetivo.
private-peerLa política envía rutas a Device Exchange-2.exchange-peer
En el ejemplo, solo se deben enviar dos rutas a Device Exchange-2:
Ruta de agregado que representa el espacio de enrutamiento del AS 64510 de 172.16.32.0/21. Esta ruta se configura como una ruta agregada localmente y la política la anuncia.
exchange-peerEl espacio de direcciones asignado a Cliente-2, 172.16.44.0/23. Esta ruta agregada más pequeña debe enviarse al dispositivo de intercambio -2 porque el cliente también está conectado al par del AS 64516 (Par privado del dispositivo 2).
El envío de estas dos rutas a Device Exchange-2 permite que otras redes en Internet lleguen al cliente a través del ISP o del par privado. Si solo el par privado anunciase en la red /23 mientras el ISP mantuvo solo su agregado /21, todo el tráfico destinado al cliente solo podría transitar por el AS 64516. Debido a que el cliente también quiere rutas del ISP, la ruta 172.16.44.0/23 es anunciada por el dispositivo ISP-2. Al igual que la ruta agregada más grande, la ruta 172.16.44.0/23 se configura localmente y se anuncia mediante la directiva de pares de intercambio. El término final de esa política rechaza todas las rutas, incluidas las redes de clientes específicas del ISP, las rutas del cliente desde Device Private-Peer-1, las rutas del cliente desde Device Private-Peer-2 y la tabla de enrutamiento desde Device Exchange-1. En esencia, este último término impide que el ISP realice servicios de tránsito para Internet en general.
Para configurar el dispositivo ISP-2:
Configure las interfaces del dispositivo.

En el dispositivo ISP-3, existe una política independiente para cada cliente. La directiva envía la ruta predeterminada para Cliente-1 .customer-1-peer Esta política encuentra la ruta predeterminada 0.0.0.0/0 en inet.0 y la acepta. La política también rechaza todas las demás rutas, por lo que no envía todas las rutas BGP en el enrutador ISP. La política es para el cliente-2 y contiene los mismos términos de la política, que también envían la ruta predeterminada y ninguna otra ruta BGP de tránsito.customer-2-peer Los términos adicionales de la política envían las rutas del cliente ISP al Cliente 2.customer-2-peer Debido a que hay rutas estáticas locales en el dispositivo ISP-3 que representan a clientes locales, estas rutas se envían, así como todas las demás rutas internas anunciadas al enrutador local por los otros enrutadores ISP.

Device Private-Peer-2 realiza dos funciones principales:
Anuncia rutas locales al AS 64516 tanto a los pares de intercambio como a los enrutadores ISP. La directiva anuncia las rutas estáticas locales (es decir, los clientes) del enrutador y también anuncia todas las rutas aprendidas por BGP que se originaron en el AS 64516 o en el AS 64512.
outbound-routesEstas rutas incluyen otras rutas de clientes de AS 64516 además del cliente del AS 64512. Las rutas del AS se identifican mediante criterios de coincidencia de expresión regular de ruta de AS de la política.Anuncia la ruta predeterminada 0.0.0.0/0 al enrutador del cliente del AS 64512. Para lograr esto, el par privado crea una ruta generada para 0.0.0.0/0 localmente en el enrutador. A esta ruta generada se le asigna además una política denominada , que permite que solo ciertas rutas contribuyan a la ruta generada, lo que la convierte en una ruta activa en la tabla de enrutamiento.
if-upstream-routes-existUna vez que la ruta está activa, puede enviarse al enrutador del AS 64512 mediante el BGP y las políticas configuradas. La política solo acepta la ruta 172.16.32.0/21 de Device Exchange-2 y rechaza todas las demás rutas.if-upstream-routes-existSi el par de intercambio retira la ruta 172.16.32.0/21, el par privado pierde la ruta predeterminada 0.0.0.0/0 y retira la ruta predeterminada del enrutador del cliente 64512.
