DESCRIPTION
    (ALPHA) Creates a Compute Engine delegated sub prefix.

EXAMPLES
    To create a delegated sub prefix for a global public delegated prefix:

        $ gcloud alpha compute public-delegated-prefixes \
            delegated-sub-prefixes create my-sub-prefix \
            --range=120.120.10.128/28 --public-delegated-prefix=my-pdp \
            --global-public-delegated-prefix

    To create a delegated sub prefix for a regional public delegated prefix:

        $ gcloud alpha compute public-delegated-prefixes \
            delegated-sub-prefixes create my-sub-prefix \
            --range=120.120.10.128/30 --create-addresses \
            --public-delegated-prefix=my-pdp \
            --public-delegated-prefix-region=us-east1

POSITIONAL ARGUMENTS
     NAME
        Name of the delegated sub prefix to create.

REQUIRED FLAGS
     --public-delegated-prefix=PUBLIC_DELEGATED_PREFIX
        Name of the public delegated prefix to create the delegate sub prefix
        for.

OPTIONAL FLAGS
     --allocatable-prefix-length=ALLOCATABLE_PREFIX_LENGTH
        Specify allocatable prefix length supported by this sub prefix.

     --create-addresses
        Specify if the sub prefix is delegated to create address resources in
        the delegatee project. Default is false.

     --delegatee-project=DELEGATEE_PROJECT
        Project to delegate the IPv4 range specified in --range to. If empty,
        the sub-range is delegated to the same/existing project.

     --description=DESCRIPTION
        Description of the delegated sub prefix to create.

     --mode=MODE
        Specifies the mode of this IPv6 PDP. MODE must be one of: delegation,
        external-ipv6-forwarding-rule-creation,
        external-ipv6-subnetwork-creation, internal-ipv6-subnetwork-creation.

     --range=RANGE
        IPv4 range from this public delegated prefix that should be delegated,
        in CIDR format. If not specified, the entire range ofthe public
        advertised prefix is delegated.

     At most one of these can be specified:

       --global-public-delegated-prefix
          If set, the public delegated prefix is global.

       --public-delegated-prefix-region=PUBLIC_DELEGATED_PREFIX_REGION
          Region of the public delegated prefix to create the delegate sub
          prefix for. If not specified, you might be prompted to select a
          region (interactive mode only).

          To avoid prompting when this flag is omitted, you can set the
          compute/region property:

              $ gcloud config set compute/region REGION

          A list of regions can be fetched by running:

              $ gcloud compute regions list

          To unset the property, run:

              $ gcloud config unset compute/region

          Alternatively, the region can be stored in the environment variable
          CLOUDSDK_COMPUTE_REGION.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud compute public-delegated-prefixes delegated-sub-prefixes \
            create

        $ gcloud beta compute public-delegated-prefixes \
            delegated-sub-prefixes create
