【问题描述】:
我正在使用云形成来创建 VPC。并且在创建子网时失败。我检查并相信子网是有效的。虽然我的网络知识有些欠缺。
这是我得到的错误:
00:46:49 UTC-0400 CREATE_FAILED AWS::EC2::Subnet SubnetA The CIDR '172.16.64.0/16' is invalid.
00:46:49 UTC-0400 CREATE_IN_PROGRESS AWS::EC2::RouteTable RouteTable 资源创建已启动 00:46:49 UTC-0400 CREATE_FAILED AWS::EC2::Subnet SubnetB CIDR '197.16.128.0/16' 无效。
这是我正在尝试使用的模板:
