associate-vpc-cidr-block¶

Description¶

Associates a CIDR block with your VPC. You can associate a secondary IPv4 CIDR block, an Amazon-provided IPv6 CIDR block, or an IPv6 CIDR block from an IPv6 address pool that you provisioned through bring your own IP addresses (BYOIP ). The IPv6 CIDR block size is fixed at /56.

You must specify one of the following in the request: an IPv4 CIDR block, an IPv6 pool, or an Amazon-provided IPv6 CIDR block.

For more information about associating CIDR blocks with your VPC and applicable restrictions, see VPC and subnet sizing in the Amazon Virtual Private Cloud User Guide .

Options¶

--amazon-provided-ipv6-cidr-block | --no-amazon-provided-ipv6-cidr-block (boolean)

Requests an Amazon-provided IPv6 CIDR block with a /56 prefix length for the VPC. You cannot specify the range of IPv6 addresses, or the size of the CIDR block.

--cidr-block (string)

An IPv4 CIDR block to associate with the VPC.

--vpc-id (string)

The ID of the VPC.

--ipv6-cidr-block-network-border-group (string)

The name of the location from which we advertise the IPV6 CIDR block. Use this parameter to limit the CIDR block to this location.

You must set AmazonProvidedIpv6CidrBlock to true to use this parameter.

You can have one IPv6 CIDR block association per network border group.

--ipv6-pool (string)

The ID of an IPv6 address pool from which to allocate the IPv6 CIDR block.

--ipv6-cidr-block (string)

An IPv6 CIDR block from the IPv6 address pool. You must also specify Ipv6Pool in the request.

To let Amazon choose the IPv6 CIDR block for you, omit this parameter.

--ipv4-ipam-pool-id (string)

Associate a CIDR allocated from an IPv4 IPAM pool to a VPC. For more information about Amazon VPC IP Address Manager (IPAM), see What is IPAM? in the Amazon VPC IPAM User Guide .

--ipv4-netmask-length (integer)

The netmask length of the IPv4 CIDR you would like to associate from an Amazon VPC IP Address Manager (IPAM) pool. For more information about IPAM, see What is IPAM? in the Amazon VPC IPAM User Guide .

--ipv6-ipam-pool-id (string)

Associates a CIDR allocated from an IPv6 IPAM pool to a VPC. For more information about Amazon VPC IP Address Manager (IPAM), see What is IPAM? in the Amazon VPC IPAM User Guide .

--ipv6-netmask-length (integer)

The netmask length of the IPv6 CIDR you would like to associate from an Amazon VPC IP Address Manager (IPAM) pool. For more information about IPAM, see What is IPAM? in the Amazon VPC IPAM User Guide .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Example 1: To associate an Amazon-provided IPv6 CIDR block with a VPC

The following associate-vpc-cidr-block example associates an IPv6 CIDR block with the specified VPC.:

aws ec2 associate-vpc-cidr-block \
    --amazon-provided-ipv6-cidr-block \
    --ipv6-cidr-block-network-border-group us-west-2-lax-1  \
    --vpc-id vpc-8EXAMPLE

Output:

{
    "Ipv6CidrBlockAssociation": {
        "AssociationId": "vpc-cidr-assoc-0838ce7d9dEXAMPLE",
        "Ipv6CidrBlockState": {
            "State": "associating"
        },
        "NetworkBorderGroup": "us-west-2-lax-1"
    },
    "VpcId": "vpc-8EXAMPLE"
}

Example 2:To associate an additional IPv4 CIDR block with a VPC

The following associate-vpc-cidr-block example associates the IPv4 CIDR block 10.2.0.0/16 with the specified VPC.

aws ec2 associate-vpc-cidr-block \
    --vpc-id vpc-1EXAMPLE \
    --cidr-block 10.2.0.0/16

Output:

{
    "CidrBlockAssociation": {
        "AssociationId": "vpc-cidr-assoc-2EXAMPLE",
        "CidrBlock": "10.2.0.0/16",
        "CidrBlockState": {
            "State": "associating"
        }
    },
    "VpcId": "vpc-1EXAMPLE"
}
