Terraform-Beispiele für HA VPN über Cloud Interconnect

Sie können die folgenden Terraform-Beispiele verwenden, um HA VPN über Cloud Interconnect bereitzustellen.

In den Beispielen wird vorausgesetzt, dass Sie bereits zwei Dedicated Interconnect-Verbindungen in zwei Edge-Verfügbarkeitsdomains (Zonen) bereitgestellt haben.

Informationen zum Anwenden oder Entfernen einer Terraform-Konfiguration finden Sie unter Grundlegende Terraform-Befehle.

Beispiele

Beispiel mit 5 Gbit/s

Im folgenden Terraform-Beispiel wird eine HA VPN über Cloud Interconnect-Bereitstellung mit zwei 5-Gbit/s-VLAN-Anhängen bereitgestellt.
