disassociate-vpc-cidr-block¶

Description¶

Disassociates a CIDR block from a VPC. To disassociate the CIDR block, you must specify its association ID. You can get the association ID by using DescribeVpcs . You must detach or delete all gateways and resources that are associated with the CIDR block before you can disassociate it.

You cannot disassociate the CIDR block with which you originally created the VPC (the primary CIDR block).

Synopsis¶

  disassociate-vpc-cidr-block
--association-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--association-id (string)

The association ID for the CIDR block.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To disassociate an IPv6 CIDR block from a VPC

This example disassociates an IPv6 CIDR block from a VPC using the association ID for the CIDR block.

Command:

aws ec2 disassociate-vpc-cidr-block --association-id vpc-cidr-assoc-eca54085

Output:

{
  "Ipv6CidrBlockAssociation": {
      "Ipv6CidrBlock": "2001:db8:1234:1a00::/56",
      "AssociationId": "vpc-cidr-assoc-eca54085",
      "Ipv6CidrBlockState": {
          "State": "disassociating"
      }
  },
  "VpcId": "vpc-a034d6c4"
}

To disassociate an IPv4 CIDR block from a VPC

This example disassociates an IPv4 CIDR block from a VPC.

Command:

aws ec2 disassociate-vpc-cidr-block --association-id vpc-cidr-assoc-0287ac6b

Output:

{
  "CidrBlockAssociation": {
      "AssociationId": "vpc-cidr-assoc-0287ac6b",
      "CidrBlock": "172.18.0.0/16",
      "CidrBlockState": {
          "State": "disassociating"
      }
  },
  "VpcId": "vpc-27621243"
}
