# 创建自定义路由

全球 VPC 中的路由决定了数据包在 VPC 内部和外部的传输方向，指定了哪些数据包发送到哪些目的地。您可以自定义静态路由并将流量路由到网卡。

## 操作步骤

1. 选择您希望关联静态路由的全球 VPC。
2. 设置目标地址。\
   目标范围是一个单独的 IPv4 或 IPv6 范围，且不能与现有的子网路由完全匹配或包含在内。
3. 设置路由的优先级。\
   值范围从 0 到 65535。值越小，优先级越高。
4. 选择下一跳实例或网卡。\
   如果您选择实例作为下一跳，数据包将发送到该实例的主网卡。
5. 标记路由。

## 更多操作

您可以在 **路由** > **操作** 中删除静态路由。

子网路由仅在相关子网被删除时才会自动删除。
