Ejemplo: Servicios de próxima generación entre chasis Alta disponibilidad de estado para TDR y firewall de inspección de estado
En este ejemplo, se muestra cómo configurar la alta disponibilidad entre chasis de los servicios de próxima generación para firewalls con estado y servicios TDR.
Descripción general
Dos enrutadores están configurados de manera idéntica para facilitar la tolerancia a fallos de estado para servicios de firewall y TDR en caso de falla de un chasis.
Configuración
Para configurar la alta disponibilidad entre chasis para este ejemplo, realice estas tareas:
- Configuración rápida de CLI
- Configuración de interfaces para chasis 1.
- Configurar la información de enrutamiento para el chasis 1
- Configuración de TDR y firewall de inspección de estado para el chasis 1
- Configuración del conjunto de servicios
- Configuración de interfaces para el chasis 2
- Configurar la información de enrutamiento para el chasis 2
Configuración rápida de CLI
Para configurar rápidamente este ejemplo en los enrutadores, copie los siguientes comandos y péguelos en la ventana terminal del enrutador después de eliminar los saltos de línea y sustituirlos por información de interfaz específica de su sitio.
La siguiente configuración es para el chasis 1.
