Cet exemple de configuration illustre une conception de réseau IPSec en étoile entre trois routeurs. Cette configuration diffère des autres configurations de réseau en étoile, car dans cet exemple, la communication est activée entre les sites en étoile en passant par le hub. En d'autres termes, il n'y a pas de tunnel IPsec direct entre les deux routeurs en étoile. Tous les paquets sont envoyés à travers le tunnel au routeur central qui les redistribue dans le tunnel IPsec partagé avec l'autre routeur en étoile. Cette configuration est possible suite à la résolution du bogue Cisco ID CSCdp09904 (clients enregistrés uniquement). Cette correction a été intégrée dans la version 12.2(5) du logiciel Cisco IOS® et cette version est la condition minimum requise pour cette configuration.
Afin de configurer le tunnel GRE (Generic Routing Encapsulation) sur IPSec avec OSPF, référez-vous à Configuration d'un tunnel GRE sur IPSec avec OSPF.
Afin de configurer la configuration de base du pare-feu Cisco IOS® sur un tunnel GRE avec traduction d'adresses de réseau (NAT), référez-vous à Configuration d'IPSec routeur à routeur (clés prépartagées) sur le tunnel GRE avec pare-feu IOS et NAT.
Ce document exige une connaissance de base du protocole IPSec. Référez-vous à Introduction au cryptage de sécurité IP (IPSec) pour en savoir plus sur IPsec.
L'objectif de ce document est de s'assurer que le chiffrement est effectué entre ces routeurs :
172.16.1.0/24 (Spoke 1) à 10.1.1.0/24 (Hub)
192.168.1.0/24 (Spoke 2) à 10.1.1.0/24 (Hub)
172.16.1.0/24 (Spoke 1) à 192.168.1.0/24 (Spoke 2)

Si vous devez ajouter un autre routeur en étoile (Spoke3) au routeur concentrateur existant en plus de Spoke1 et Spoke2, il suffit de créer un nouveau tunnel LAN à LAN (L2L) à partir du concentrateur vers Spoke3. Cependant, comme une seule carte de chiffrement peut être configurée par interface physique, vous devez utiliser le même nom de carte de chiffrement lors de l'ajout de ce tunnel. Cela est possible lorsque vous utilisez des numéros de ligne différents pour chaque site distant.
Remarque : Il peut être nécessaire de supprimer la carte de chiffrement et de la réappliquer à l'interface lorsque la nouvelle entrée de tunnel est ajoutée. Lorsque la carte de chiffrement est supprimée, tous les tunnels actifs sont effacés.

Afin de vérifier cette configuration, essayez une commande ping étendue provenant de l'adresse d'interface ethernet1 sur Spoke 1, destinée à l'adresse d'interface ethernet1 dans Spoke 2.

show crypto ipsec sa - Affiche les paramètres utilisés par les associations de sécurité (SA) IPSec actuelles.
show crypto isakmp sa — Affiche toutes les SA IKE en cours au niveau d'un homologue.
show crypto engine connections active : affiche le nombre de paquets transmis sur chaque SA IPSec.
Ce résultat provient de la commande show crypto engine connections active exécutée sur le routeur Hub.

À partir de cet exemple, vous pouvez voir que chaque tunnel a chiffré et déchiffré 10 paquets, ce qui prouve que le trafic est passé par le routeur concentrateur.
Remarque : deux SA IPsec sont créées pour chaque homologue (une dans chaque direction). Par exemple, dans le routeur concentrateur, quatre SA IPsec sont créées pour deux homologues.
Cette section fournit des informations que vous pouvez utiliser pour dépanner votre configuration.
Remarque : Consulter les renseignements importants sur les commandes de débogage avant d’utiliser les commandes de débogage.
debug crypto ipsec : Cette commande affiche les négociations IPSec de la phase 2.
debug crypto isakmp - Affiche les négociations ISAKMP de la phase 1.
debug crypto engine - Montre le trafic crypté.
clear crypto isakmp : efface les SA liées à la phase 1.
clear crypto sa : efface les SA liées à la phase 2.
Il s'agit de la sortie du routeur concentrateur des commandes debug crypto ipsec et debug crypto isakmp.
