Este documento describe cómo configurar un diseño de redundancia completa para oficinas remotas que se conectan a un Data Center a través de una VPN basada en IPSec a través de un medio de red inseguro, como Internet.
No hay requisitos específicos para este documento.
La información en este documento se basa en estos componentes tecnológicos:
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.
Al diseñar soluciones de acceso remoto para el Data Center, la alta disponibilidad (HA) suele ser un requisito clave para las aplicaciones de usuario críticas.
La solución que se presenta en este documento permite una rápida detección y recuperación de situaciones de falla en las que uno de los concentradores de terminación de VPN deja de funcionar debido a problemas de recarga, actualización o energía. Todos los routers de oficinas remotas (spokes) utilizan el otro hub operativo inmediatamente después de detectar tal falla.
Estas son las ventajas de este diseño:
Esta sección proporciona escenarios de ejemplo y describe cómo configurar un diseño de redundancia completa para oficinas remotas que se conectan al Data Center a través de VPN basada en IPSec a través de un medio de red inseguro.
Nota: Use la Command Lookup Tool (clientes registrados solamente) para obtener más información sobre los comandos usados en esta sección.
Esta es la topología de red que se utiliza en este documento:
Nota: Todos los routers que se utilizan en esta topología ejecutan Cisco IOS versión 15.2(4)M1, y Internet Cloud utiliza un esquema de direcciones de 172.16.0.0/24.
En un escenario operativo normal, cuando todos los routers están activos y en funcionamiento, todos los routers radiales enrutan todo el tráfico a través del hub predeterminado (R1-HUB1). Esta preferencia de ruteo se logra cuando la preferencia local predeterminada de BGP se establece en 200 (consulte las secciones que siguen para obtener detalles). Esto se puede ajustar en función de los requisitos de implementación, como el equilibrio de carga del tráfico.
Si R3-Spoke1 inicia una conexión a R4-Spoke2, se crea un túnel dinámico spoke-to-spoke con la configuración de conmutación corta.
Consejo: Para obtener más detalles, consulte la guía de configuración Configuración de FlexVPN Spoke to Spoke.
Si R3-Spoke1 está conectado sólo a R1-HUB1 y R4-Spoke2 está conectado sólo a R2-HUB2, todavía se puede lograr una conexión directa de radio a radio con el túnel GRE punto a punto que se ejecuta entre los concentradores. En este caso, la trayectoria de tráfico inicial entre R3-Spoke1 y R4-Spoke2 parece similar a esta:
Dado que R1-Hub1 recibe el paquete en la interfaz de acceso virtual, que tiene el mismo ID de red de protocolo de resolución de salto siguiente (NHRP) que en el túnel GRE, la indicación de tráfico se envía hacia el R3-Spoke1. Esto desencadena la creación del túnel dinámico spoke-to-spoke:
Esta es la tabla de ruteo R1-HUB1 en un escenario operativo normal:
