如果您希望配置一个 [三层网络](/welcome/cn/cloud-networking/overview/concepts.md#cloud-router) 并在 [全球 VPC](/welcome/cn/bare-metal/overview/private-network/virtual-private-cloud.md) 中运行您的实例，请选择一个现有的全球 VPC 或创建一个新的。详情请参阅 [创建全球 VPC](/welcome/cn/bare-metal/get-started/create-a-virtual-private-cloud.md)。

如果您希望配置一个 [二层网络](/welcome/cn/cloud-networking/overview/concepts.md#private-connect) 并在 [子网](/welcome/cn/bare-metal/overview/private-network/subnet.md) 中运行您的实例，请选择一个现有的子网或创建一个新的。详情请参阅 [创建子网](/welcome/cn/bare-metal/get-started/create-a-subnet.md)。
