ExpressRoute 先决条件和清单ExpressRoute prerequisites & checklist

若要使用 ExpressRoute 连接到 Azure 云服务,需确认是否符合以下部分中所列的要求。To connect to Azure cloud services using ExpressRoute, you need to verify that the following requirements listed in the following sections have been met.

Azure 帐户Azure account

  • 使用中的有效 Azure 帐户。A valid and active Microsoft Azure account. 需有此帐户才能设置 ExpressRoute 线路。This account is required to set up the ExpressRoute circuit. ExpressRoute 线路是 Azure 订阅中的资源。ExpressRoute circuits are resources within Azure subscriptions.

连接服务提供商Connectivity provider

网络要求Network requirements

  • 每个对等互连位置的冗余性:Microsoft 要求在 Microsoft 的路由器和每个 ExpressRoute 线路上的对等互连路由器之间建立冗余的 BGP 会话(即使只有一个到云交换的物理连接)。Redundancy at each peering location: Microsoft requires redundant BGP sessions to be set up between Microsoft’s routers and the peering routers on each ExpressRoute circuit (even when you have just one physical connection to a cloud exchange).
  • 灾难恢复的冗余:Microsoft 强烈建议你在不同的对等互连位置设置至少两条 ExpressRoute 线路,避免单点故障。Redundancy for Disaster Recovery: Microsoft strongly recommends you set up at least two ExpressRoute circuits in different peering locations to avoid a single point of failure.
  • 路由:你或提供商需设置和管理针对路由域的 BGP 会话,具体取决于连接到 Microsoft 云的方式。Routing: depending on how you connect to the Microsoft Cloud, you or your provider needs to set up and manage the BGP sessions for routing domains. 某些以太网连接服务提供商或云交换服务提供商可能会以增值服务的形式提供 BGP 管理。Some Ethernet connectivity providers or cloud exchange providers may offer BGP management as a value-add service.
  • NAT:Microsoft 只能通过 Microsoft 对等互连接受公共 IP 地址。NAT: Microsoft only accepts public IP addresses through Microsoft peering. 如果使用的是本地网络中的专用 IP 地址,你或提供商需使用 NAT将专用 IP 地址转换为公共 IP 地址。If you are using private IP addresses in your on-premises network, you or your provider needs to translate the private IP addresses to the public IP addresses using the NAT.
