我在 AWS 上有 2 个 VPC VPC-A 172.31.0.016，VPC-B 172.17.0.0/24
我已经创建了 VPC 对等互连，并且可以访问正在运行的所有服务，VPC-B反之亦然VPC-A。
VPC-B现在我创建了一个带有地址的flannel 虚拟网络172.17.0.0/16
etcdctl set /coreos.com/network/config '{ "Network": "10.17.0.0/16", "Backend": {"Type": "aws-vpc"} }'
后端aws-vpc正在运行，因为路由VPC-B表中出现了路由，并且 VPC 中的机器可以访问托管在 flannel 网络上的服务，但我无法从 访问172.17.0.0/16主机VPC-A。
VPC-A路由表：
