Ejemplo: Configurar VPN IPSec en multinodo activo-activo de alta disponibilidad en una red de capa 3
RESUMEN En este ejemplo se muestra cómo configurar y comprobar VPN IPsec para la configuración de alta disponibilidad de multinodo activo-activo.
Visión general
En la alta disponibilidad de varios nodos, los firewalls de la serie SRX participantes funcionan como nodos independientes en una red de capa 3. Los nodos están conectados a una infraestructura adyacente que pertenece a diferentes redes. Un vínculo lógico cifrado entre chasis (ICL) conecta los nodos a través de una red enrutada. Los nodos participantes se respaldan entre sí para garantizar una conmutación por error rápida y sincronizada en caso de fallo del sistema o del hardware.
Puede operar la alta disponibilidad de varios nodos en modo activo-activo con soporte de varios grupos de redundancia de servicios (SRG). En este modo, algunas SRG permanecen activas en un nodo y algunas SRG permanecen activas en otro nodo.
La alta disponibilidad de varios nodos admite VPN IPsec en modo activo-activo con varias SRG (SRG1+). En este modo, puede establecer varios túneles activos desde ambos nodos, en función de la actividad de SRG. La alta disponibilidad multinodo establece un túnel IPsec y realiza intercambios de claves asociando la dirección IP de terminación (que también identifica los túneles que terminan en ella) al SRG. Dado que diferentes SRG1+ pueden estar en estado activo o en estado de respaldo en cada uno de los dispositivos, la alta disponibilidad de multinodo dirige el tráfico coincidente de manera efectiva al SRG1 activo correspondiente. Dado que diferentes SRG pueden estar activos en diferentes nodos, los túneles que pertenecen a estos SRG aparecen en ambos nodos de forma independiente.
Nota:
Admitimos una configuración de dos nodos en la solución Multinode High Availability.
Requisitos
En este ejemplo se utilizan los siguientes componentes de hardware y software:
Dos firewalls de la serie SRX (los dispositivos compatibles son SRX5400, SRX5600 y SRX5800 con SPC3, IOC3, SCB3, SCB4 y RE3)
Junos OS versión 22.4R1
En este ejemplo, hemos utilizado dos plataformas de enrutamiento de la serie MX de Juniper Networks como enrutadores ascendentes y descendentes.
Antes de empezar
Configure el filtrado de firewall sin estado y la calidad de servicio (QoS) según los requisitos de su red y tenga las políticas de seguridad adecuadas para administrar el tráfico en su red.
En una implementación típica de alta disponibilidad, tiene varios enrutadores y conmutadores en los lados norte y sur de la red. Para este ejemplo, estamos usando dos enrutadores a cada lado de los firewalls de la serie SRX. Asegúrese de haber configurado los enrutadores ascendentes y descendentes según los requisitos de su red.
Instale el paquete IKE de Junos en los firewalls de la serie SRX mediante el
request system software add optional://junos-ike.tgzcomando. Eljunos-ikepaquete se incluye en los paquetes de software de Junos (versión 20.4R1 de Junos OS en adelante).
Topología
La figura 1 muestra la topología utilizada en este ejemplo.
Figura 1: Alta disponibilidad de múltiples nodos en redes
de capa 3
de capa 3
Como se muestra en la topología, dos firewalls de la serie SRX (SRX-1 y SRX-2) están conectados a enrutadores adyacentes en el lado de confianza y no confianza que forman una vecindad BGP. Un vínculo lógico cifrado entre chasis (ICL) conecta los nodos a través de una red enrutada. Los nodos se comunican entre sí mediante una dirección IP enrutable (dirección IP flotante) a través de la red.
El dispositivo SRX-03 actúa como un dispositivo par para la configuración de alta disponibilidad de multinodo y establece túneles VPN IPsec con dispositivos SRX-01 y SRX-02.
Realizará las siguientes tareas para crear una configuración de alta disponibilidad de multinodo:
- Configure un par de firewalls de la serie SRX como nodos locales y pares mediante la asignación de ID.
- Configure grupos de redundancia de servicios (SRG1 y SRG2).
- Configure una interfaz de circuito cerrado (lo0.0) para alojar la dirección IP flotante y llegar a la puerta de enlace del mismo nivel. El uso de la interfaz de circuito cerrado garantiza que, en un momento dado, el tráfico de los enrutadores adyacentes se dirigirá hacia la dirección IP flotante (es decir, hacia el nodo activo).
- Configurar sondeos IP para la determinación de la actividad y el cumplimiento
- Configure una ruta de señal necesaria para la aplicación de la actividad y utilícela junto con la política de existencia de ruta.
- Configure un perfil de VPN para el tráfico de alta disponibilidad (ICL) mediante IKEv2.
- Configurar las opciones de supervisión de BFD
- Configurar una directiva de enrutamiento y opciones de enrutamiento
- Configure interfaces y zonas de acuerdo con sus requisitos de red. Debe permitir servicios como IKE para el cifrado de vínculos y SSH para la sincronización de la configuración como servicios del sistema de entrada de host en la zona de seguridad asociada a la ICL.
-
Cree una configuración de grupo para VPN IPsec en dispositivos SRX-01 y SRX-02 para establecer un túnel con dispositivo par VPN (SRX-03). Los grupos de configuración permiten aplicar elementos comunes que se reutilizan dentro de la misma configuración.
- Configure las opciones de VPN IPsec para establecer túneles con el dispositivo SRX-03 y habilite la sincronización de configuración de VPN IPsec en ambos dispositivos (SRX-01 y SRX-02) mediante la opción [grupos].
- Configure el dispositivo par VPN con opciones de VPN IPsec.
Para el vínculo entre chasis (ICL), se recomienda la siguiente configuración:
-
En general, puede utilizar Ethernet agregada (AE) o un puerto Ethernet de ingresos en los firewalls de la serie SRX para configurar una conexión ICL. En este ejemplo, hemos utilizado puertos GE para la ICL. También hemos configurado una instancia de enrutamiento para la ruta de ICL a fin de garantizar la máxima segmentación.
- No utilice los puertos HA dedicados (puertos de control y de estructura) si están disponibles en el firewall de la serie SRX).
- Conjunto de MTU de 1514
- Permitir los siguientes servicios en la zona de seguridad asociada a las interfaces utilizadas para ICL
-
IKE, alta disponibilidad, SSH
-
Protocolos en función del protocolo de enrutamiento que necesite.
-
BFD para monitorear las rutas vecinas.
-
Puede configurar las siguientes opciones en SRG0 y SRG1+:
Puede configurar las siguientes opciones en SRG0 y SRG1:
-
SRG1: Ruta de señal activa/de respaldo, tipo de despliegue, prioridad de actividad, preferencia, dirección IP virtual (para despliegues de puerta de enlace predeterminada), sondeo de actividad y paquete de proceso en copia de seguridad.
-
SRG1: monitoreo de BFD, monitoreo de IP y opciones de monitoreo de interfaz en SRG1.
-
SRG0: opciones de ruta de apagado en caso de error e instalación en caso de error.
Cuando configure las opciones de supervisión (BFD, IP o Interfaz) en SRG1, se recomienda no configurar la opción de apagado por error en SRG0.
-
SRG1: Ruta de señal activa/de respaldo, tipo de despliegue, prioridad de actividad, preferencia, dirección IP virtual (para despliegues de puerta de enlace predeterminada), sondeo de actividad y paquete de proceso en copia de seguridad.
-
SRG1: monitoreo de BFD, monitoreo de IP y opciones de monitoreo de interfaz en SRG1.
-
SRG0: opciones de ruta de apagado en caso de error e instalación en caso de error.
Cuando configure las opciones de supervisión (BFD, IP o Interfaz) en SRG1, se recomienda no configurar la opción de apagado por error en SRG0.

Configuración
Procedimiento paso a paso
Mostramos la configuración de SRX-01 en el procedimiento paso a paso.
En el ejemplo siguiente es necesario navegar por varios niveles en la jerarquía de configuración. Para obtener instrucciones sobre cómo hacerlo, consulte Uso del editor de CLI en el modo de configuración de la Guía del usuario de CLI.
Configurar interfaces.

Utilice las interfaces ge-0/0/3 y ge-0/0/4 para conectarse a los enrutadores ascendentes y descendentes y utilice la interfaz ge-0/0/2 para configurar la ICL.
Configure las interfaces de circuito cerrado.

Configure la ruta de señal activa 10.39.1.1 (SRG1) y 10.49.1.1 (SRG2) con la condición de coincidencia de ruta (
if-route-exists). La alta disponibilidad de varios nodos agrega esta ruta a la tabla de enrutamiento cuando el nodo se mueve al rol activo. El nodo también comienza a anunciar la ruta de preferencia más alta. Configure la ruta de señal de respaldo (10.39.1.2 y 10.49.1.2) para anunciar el nodo de respaldo con prioridad media. En caso de fallo, el enlace de alta disponibilidad deja de funcionar y el nodo activo actual libera su función principal y elimina la ruta de señal activa. Ahora, el nodo de copia de seguridad detecta la condición a través de sus sondeos y pasa al rol activo. La preferencia de ruta se intercambia para dirigir todo el tráfico al nuevo nodo activoConfigure las opciones de las sesiones de emparejamiento BFD y especifique temporizadores de detección de vida.

Cree una política de seguridad.
[edit] user@srx-3# set security policies default-policy permit-all
En este ejemplo, hemos configurado una política para permitir todo el tráfico. Le recomendamos encarecidamente que cree políticas de seguridad de acuerdo con los requisitos de su red para permitir el tráfico permitido por la política de su organización y denegar el resto del tráfico. En este ejemplo, solo hemos usado la directiva predeterminada para el propósito de la demostración.
Configure las interfaces.

Significado
El resultado del comando proporciona la siguiente información:
Los detalles de la puerta de enlace local y la puerta de enlace remota.
El par SA IPsec para cada subproceso en PIC.
Modo de cifrado de vínculo HA (como se muestra en la línea siguiente):
HA Link Encryption Mode: Multi-NodeAlgoritmos de autenticación y cifrado utilizados
PRECAUCIÓN:
El intervalo IP (180.100.1.x) que se muestra en el resultado del comando sirve como selector de tráfico IPsec de ICL. El sistema asigna dinámicamente este rango de IP, y es esencial no alterarlo ni modificarlo. Además, BFD (detección de reenvío bidireccional) se habilitará automáticamente para el rango más amplio de IP 180.x.x.x.
Verificar estadísticas de túnel de cifrado de vínculos
Propósito
Verifique las estadísticas del túnel de cifrado de vínculos en los nodos activos y de respaldo.
Acción
Ejecute el siguiente comando en SRX-01:
user@srx-01> show security ipsec statistics ha-link-encryption ESP Statistics: Encrypted bytes: 106294156 Decrypted bytes: 51961287 Encrypted packets: 979531 Decrypted packets: 989651 AH Statistics: Input bytes: 0 Output bytes: 0 Input packets: 0 Output packets: 0 Errors: AH authentication failures: 0, Replay errors: 0 ESP authentication failures: 0, ESP decryption failures: 0 Bad headers: 0, Bad trailers: 0 Invalid SPI: 0, TS check fail: 0 Exceeds tunnel MTU: 0 Discarded: 0
Significado
Si ve problemas de pérdida de paquetes en una VPN, puede ejecutar el show security ipsec statistics ha-link-encryption comando varias veces para comprobar que los contadores de paquetes cifrados y descifrados se incrementan. También debe comprobar si los otros contadores de errores se incrementan.
Utilice el clear security ipsec security-associations ha-link-encryption comando para borrar todas las estadísticas de IPsec.
