Creates a secondary subnet in a secondary network.
A secondary subnet CIDR block must not overlap with the CIDR block of an existing secondary subnet in the secondary network. After you create a secondary subnet, you can't change its CIDR block.
The allowed size for a secondary subnet CIDR block is between /28 netmask (16 IP addresses) and /12 netmask (1,048,576 IP addresses). Amazon reserves the first four IP addresses and the last IP address in each secondary subnet for internal use.
This is an asynchronous operation using the standard naming convention for .NET 4.7.2 or higher.
