通过 AWS CloudFormation 创建 Amazon VPC 时的"CIDR is invalid"



我正在使用AWS上的PCI DSS-快速入门模板。它可以正常工作，但当我将ProductionVPC编辑为自己选择的自定义IP时，堆栈会失败。我的子网如下：

(MAIN) ProductionVPC: 172.21.32.0/19
pDMZSubnetACIDR: 172.21.48.0/23
pDMZSubnetBCIDR: 172.21.50.0/23
pAppPrivateSubnetACIDR: 172.21.32.0/21
pAppPrivateSubnetBCIDR: 172.21.40.0/21
pDBPrivateSubnetACIDR: 172.21.52.0/23
pDBPrivateSubnetBCIDR: 172.21.54.0/23

当我运行这个时，堆栈失败，我看到上面的子网出现以下几个错误，如下所示：

CIDR"172.21.52.0/23"无效。(服务：AmazonEC2；状态代码：400；错误代码：InvalidSubnet。Range；请求ID:d1998b65-396e-48e7-863a-2c1e0919fbff；代理：null(

我的子网选择有问题吗？我没有看到任何重叠，但我可能遗漏了一些东西。

更新：我正在添加整个代码片段。原始的Quickstart模板在这里：

下面是我更新的模板。我只更新了ProductionVPCTemplate和ManagementVPCTemplateCIDR块，所以我只包含了这两个资源。您可以复制并粘贴到上面的原始模板中。请注意，Management VPC CIDR块可以正常工作——如果我添加这些块并保留其他所有内容，堆栈就会创建。但如果我只添加生产专有网络CIDR块，那么它就会失败——所以我把它缩小到生产专有网络。
