Exemple : Configuration d’un VPN IPSec en haute disponibilité multinodale active-active dans un réseau de couche 3
Cet exemple montre comment configurer et vérifier le VPN IPsec pour une configuration de haute disponibilité multi nodale active-active.
Vue d’ensemble
En haute disponibilité multi-nœuds, les pare-feu SRX Series participants fonctionnent comme des nœuds indépendants dans un réseau de couche 3. Les nœuds sont connectés à des infrastructures adjacentes appartenant à différents réseaux. Une liaison logique interchâssis (ICL) chiffrée relie les nœuds sur un réseau routé. Les nœuds participants se sauvegardent mutuellement pour assurer un basculement rapide et synchronisé en cas de défaillance du système ou du matériel.
Vous pouvez utiliser la haute disponibilité multinodale en mode actif-actif avec la prise en charge de plusieurs groupes de redondance de services (SRG). Dans ce mode, certains SRG restent actifs sur un nœud et d’autres restent actifs sur un autre nœud.
La haute disponibilité multinodale prend en charge le VPN IPsec en mode actif-actif avec plusieurs SRG (SRG1+). Dans ce mode, vous pouvez établir plusieurs tunnels actifs à partir des deux nœuds, en fonction de l’activité SRG. La haute disponibilité multi nodale établit un tunnel IPsec et effectue des échanges de clés en associant l’adresse IP de terminaison (qui identifie également les tunnels se terminant dessus) à la passerelle de recherche. Étant donné que différents SRG1+ peuvent être en état actif ou en état de sauvegarde sur chacun des appareils, la haute disponibilité multinodale dirige efficacement le trafic correspondant vers le SRG1 actif correspondant. Étant donné que différents SRG peuvent être actifs sur différents nœuds, les tunnels appartenant à ces SRG apparaissent sur les deux nœuds de manière indépendante.
Remarque :
Nous prenons en charge une configuration à deux nœuds dans la solution de haute disponibilité multi-nœuds.
Exigences
Cet exemple utilise les composants matériels et logiciels suivants :
Deux pare-feu SRX Series (les appareils pris en charge sont SRX5400, SRX5600 et SRX5800 avec SPC3, IOC3, SCB3, SCB4 et RE3)
Junos OS version 22.4R1
Dans cet exemple, nous avons utilisé deux plates-formes de routage MX Series de Juniper Networks comme routeurs en amont/en aval.
Avant de commencer
Configurez le filtrage du pare-feu sans état et la qualité de service (QoS) en fonction des exigences de votre réseau, et disposez de stratégies de sécurité appropriées pour gérer le trafic sur votre réseau.
Dans un déploiement haute disponibilité classique, vous disposez de plusieurs routeurs et commutateurs sur les côtés nord et sud du réseau. Pour cet exemple, nous utilisons deux routeurs de part et d’autre des pare-feu SRX Series. Assurez-vous d'avoir configuré les routeurs en amont et en aval en fonction des exigences de votre réseau.
Installez le package Junos IKE sur vos pare-feu SRX Series à l’aide de la
request system software add optional://junos-ike.tgzcommande. Lejunos-ikepackage est inclus dans vos packages logiciels Junos (Junos OS version 20.4R1 et ultérieure).
Topologie
La figure 1 illustre la topologie utilisée dans cet exemple.
Figure 1 : Haute disponibilité multinodale dans un réseau
de couche 3
de couche 3
Comme le montre la topologie, deux pare-feu SRX Series (SRX-1 et SRX-2) sont connectés à des routeurs adjacents côté confiance et non confiance, formant un voisinage BGP. Une liaison logique interchâssis (ICL) chiffrée relie les nœuds sur un réseau routé. Les nœuds communiquent entre eux à l’aide d’une adresse IP routable (adresse IP flottante) sur le réseau.
L’équipement SRX-03 agit comme un appareil homologue à la configuration haute disponibilité multi nodale et établit des tunnels VPN IPsec avec les appareils SRX-01 et SRX-02.
Vous allez effectuer les tâches suivantes pour créer une configuration haute disponibilité multi nodale :
- Configurez une paire de pare-feu SRX Series en tant que nœuds locaux et pairs en attribuant des ID.
- Configurez les groupes de redondance des services (SRG1 et SRG2).
- Configurez une interface de bouclage (lo0.0) pour héberger l’adresse IP flottante et atteindre la passerelle homologue. L’utilisation de l’interface de bouclage garantit qu’en tout point, le trafic des routeurs adjacents sera dirigé vers l’adresse IP flottante (c’est-à-dire vers le nœud actif).
- Configurer les sondes IP pour la détermination et l’application de l’activité
- Configurez une route de signal requise pour l’application de l’activité et utilisez-la avec la stratégie Route Exist.
- Configurez un profil VPN pour le trafic haute disponibilité (ICL) à l’aide d’IKEv2.
- Configurer les options de surveillance BFD
- Configurer une politique de routage et des options de routage
- Configurez les interfaces et les zones en fonction des besoins de votre réseau. Vous devez autoriser des services tels que IKE pour le chiffrement des liens et SSH pour la synchronisation de la configuration en tant que services système entrants sur l’hôte sur la zone de sécurité associée à la liste ICL.
-
Créez une configuration de groupe pour le VPN IPsec sur les appareils SRX-01 et SRX-02 afin de configurer un tunnel avec un appareil homologue VPN (SRX-03). Les groupes de configuration vous permettent d’appliquer des éléments communs qui sont réutilisés dans la même configuration.
- Configurez les options VPN IPsec pour établir des tunnels avec l’appareil SRX-03 et activez la synchronisation de la configuration VPN IPsec sur les deux appareils (SRX-01 et SRX-02) à l’aide de l’option [groups].
- Configurer un appareil homologue VPN avec des options VPN IPsec.
Pour la liaison interchâssis (ICL), nous recommandons la configuration suivante :
-
En général, vous pouvez utiliser Aggregated Ethernet (AE) ou un port Ethernet payant sur les pare-feu SRX Series pour configurer une connexion ICL. Dans cet exemple, nous avons utilisé des ports GE pour l'ICL. Nous avons également configuré une instance de routage pour le chemin ICL afin d'assurer une segmentation maximale.
- N’utilisez pas les ports HA dédiés (ports de contrôle et de fabric) s’ils sont disponibles sur votre pare-feu SRX Series).
- Set MTU de 1514
- Autoriser les services suivants sur la zone de sécurité associée aux interfaces utilisées pour ICL
-
IKE, haute disponibilité, SSH
-
en fonction du protocole de routage dont vous avez besoin.
-
BFD pour surveiller les routes voisines.
-
Vous pouvez configurer les options suivantes sur SRG0 et SRG1+ :
Vous pouvez configurer les options suivantes sur SRG0 et SRG1 :
-
SRG1 : Route du signal actif/de secours, type de déploiement, priorité d’activité, préemption, adresse IP virtuelle (pour les déploiements de passerelle par défaut), sondage d’activité et traitement des paquets de secours.
-
SRG1 : options de surveillance BFD, de surveillance IP et de surveillance d’interface sur SRG1.
-
SRG0 : options de route d’arrêt en cas d’échec et d’installation en cas d’échec.
Lorsque vous configurez les options de surveillance (BFD ou IP ou Interface) sous SRG1, nous vous recommandons de ne pas configurer l’option d’arrêt en cas de défaillance sous SRG0.
-
SRG1 : Route du signal actif/de secours, type de déploiement, priorité d’activité, préemption, adresse IP virtuelle (pour les déploiements de passerelle par défaut), sondage d’activité et traitement des paquets de secours.
-
SRG1 : options de surveillance BFD, de surveillance IP et de surveillance d’interface sur SRG1.
-
SRG0 : options de route d’arrêt en cas d’échec et d’installation en cas d’échec.
Lorsque vous configurez les options de surveillance (BFD ou IP ou Interface) sous SRG1, nous vous recommandons de ne pas configurer l’option d’arrêt en cas de défaillance sous SRG0.

La configuration
Procédure étape par étape
Nous montrons la configuration du SRX-01 dans la procédure étape par étape.
L’exemple suivant vous oblige à naviguer à différents niveaux dans la hiérarchie de configuration. Pour obtenir des instructions sur la procédure à suivre, consultez Utilisation de l’éditeur CLI en mode Configuration dans le Guide de l’utilisateur de la CLI.
Configurez les interfaces.

Utilisez les interfaces ge-0/0/3 et ge-0/0/4 pour vous connecter aux routeurs en amont et en aval et utilisez l’interface ge-0/0/2 pour configurer l’ICL.
Configurez les interfaces de bouclage.

Configurez la route du signal actif 10.39.1.1 (SRG1) et 10.49.1.1 (SRG2) avec la condition de correspondance de route (
if-route-exists). La haute disponibilité multinodale ajoute cette route à la table de routage lorsque le nœud passe au rôle actif. Le nœud commence également à annoncer la route de préférence la plus élevée. Configurez la route du signal de secours (10.39.1.2 et 10.49.1.2) pour annoncer le nœud de secours avec une priorité moyenne. En cas de défaillance, la liaison haute disponibilité est interrompue et le nœud actif actuel libère son rôle principal et supprime la route de signal actif. Le nœud de secours détecte alors la condition via ses sondes et passe au rôle actif. La préférence de route est permutée pour diriger tout le trafic vers le nouveau nœud actifConfigurez les options de sessions d’appairage BFD et spécifiez des minuteries de détection d’activité.

Créez une stratégie de sécurité.
[edit] user@srx-3# set security policies default-policy permit-all
Pour cet exemple, nous avons configuré une stratégie pour autoriser tout le trafic. Nous vous recommandons vivement de créer des stratégies de sécurité conformes aux exigences de votre réseau pour autoriser le trafic autorisé par votre stratégie d’organisation et refuser tout autre trafic. Nous avons utilisé la stratégie par défaut à des fins de démonstration uniquement dans cet exemple.
Configurez les interfaces.

Signification
La sortie de la commande fournit les informations suivantes :
Détails de la passerelle locale et de la passerelle distante.
Paire de SA IPsec pour chaque thread dans le PIC.
Mode de chiffrement des liens HA (comme indiqué dans la ligne suivante) :
HA Link Encryption Mode: Multi-NodeAlgorithmes d’authentification et de chiffrement utilisés
MISE EN GARDE :
La plage d’adresses IP (180.100.1.x) affichée dans la sortie de la commande sert de sélecteur de trafic ICL IPsec. Le système attribue dynamiquement cette plage d’adresses IP et il est essentiel de ne pas l’altérer ou la modifier. De plus, la détection de transfert bidirectionnel (BFD) sera automatiquement activée pour la plage IP 180.x.x.x.
Vérification des statistiques de tunnel de chiffrement des liens
Objet
Vérifiez les statistiques de tunnel de chiffrement des liens sur les nœuds actifs et de secours.
Mesures à prendre
Exécutez la commande suivante sur 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
Signification
Si vous constatez des problèmes de perte de paquets sur un VPN, vous pouvez exécuter la show security ipsec statistics ha-link-encryption commande plusieurs fois pour vérifier que les compteurs de paquets chiffrés et déchiffrés s’incrémentent. Vous devez également vérifier si les autres compteurs d’erreurs s’incrémentent.
Utilisez la clear security ipsec security-associations ha-link-encryption commande pour effacer toutes les statistiques IPsec.
