CreateSecondarySubnetResponse

This example creates a secondary subnet with a /24 CIDR block in the specified secondary network and Availability Zone.

To create a secondary subnet

var client = new AmazonEC2Client();
var response = client.CreateSecondarySubnet(new CreateSecondarySubnetRequest 
{
    AvailabilityZoneId = "use2-az1",
    ClientToken = "550e8400-e29b-41d4-a716-446655440000",
    Ipv4CidrBlock = "10.0.0.0/24",
    SecondaryNetworkId = "sn-0123456789abcdef0",
    TagSpecifications = new List<TagSpecification> {
        new TagSpecification {
            ResourceType = "secondary-subnet",
            Tags = new List<Tag> {
                new Tag {
                    Key = "Name",
                    Value = "Prod Secondary Subnet"
                },
                new Tag {
                    Key = "Environment",
                    Value = "Production"
                }
            }
        }
    }
});

string clientToken = response.ClientToken;
SecondarySubnet secondarySubnet = response.SecondarySubnet;
