Exemples Terraform pour un VPN haute disponibilité via Cloud Interconnect

Vous pouvez utiliser les exemples Terraform suivants pour déployer un VPN haute disponibilité sur Cloud Interconnect.

Dans ces exemples, vous devez déjà disposer de deux connexions Dedicated Interconnect, provisionnées dans deux domaines de disponibilité de périphérie (zones).

Pour savoir comment appliquer ou supprimer une configuration Terraform, consultez la page Commandes Terraform de base.

Exemples

Exemple de 5 Gbit/s
