Properties
Property | Type | Required | Editable | Description | Constraint |
VpcId | String | Yes | No | The ID of the VPC to which you want to add a secondary CIDR block. | None. |
Ipv6Isp | String | No | No | The type of the IPv6 CIDR block that you want to add to the VPC. | Valid values:
Note If you have the permissions to use single-ISP bandwidth, the valid values of this property are ChinaTelecom, ChinaUnicom, and ChinaMobile. |
IpVersion | String | No | No | The IP version of the IP address. | Valid values:
|
IpamPoolId | String | No | No | The ID of the IP Address Manager (IPAM) pool of the IPv4 type. | None. |
IPv6CidrBlock | String | No | No | The IPv6 CIDR block that you want to add to the VPC. | Note You must specify one of SecondaryCidrBlock and Ipv6CidrBlock. |
SecondaryCidrMask | Integer | No | No | The subnet mask that you want to use to add a secondary CIDR block from the IPAM pool to the VPC. | Note If you use an IPAM pool to add a secondary CIDR block to a VPC, you must specify at least one of SecondaryCidrBlock and SecondaryCidrMask. |
SecondaryCidrBlock | String | No | No | The secondary IPv4 CIDR block that you want to add to the VPC. | Take note of the following requirements on CIDR blocks:
The following limits apply:
Note If you do not use an IPAM pool to add a secondary CIDR block to a VPC, you must specify one of SecondaryCidrBlock and Ipv6CidrBlock. |
Return values
Fn::GetAtt
VpcId: the ID of the VPC to which the secondary CIDR block is added.

Parameters:
SecondaryCidrBlock:
Type: String
Description:
en: |-
The IPv4 CIDR block to be added. Take note of the following requirements:
You can specify one of the following standard IPv4 CIDR blocks or their subnets as the secondary IPv4 CIDR block of the VPC: 192.168.0.0/16, 172.16.0.0/12, and 10.0.0.0/8.
You can also use a custom CIDR block other than 100.64.0.0/10, 224.0.0.0/4, 127.0.0.0/8, 169.254.0.0/16, or their subnets as the secondary IPv4 CIDR block of the VPC.
The CIDR block must meet the following requirements:
The CIDR block cannot start with 0. The subnet mask must be 8 to 28 bits in length.
The CIDR block cannot overlap with the primary CIDR block or an existing secondary CIDR block of the VPC.
Note You must and can specify only one of SecondaryCidrBlock and Ipv6CidrBlock.
