        Compute Engine router

SYNOPSIS
    gcloud alpha compute routers update-interface NAME
        --interface-name=INTERFACE_NAME [--ip-address=IP_ADDRESS]
        [--ip-version=IP_VERSION] [--mask-length=MASK_LENGTH] [--region=REGION]
        [--interconnect-attachment=INTERCONNECT_ATTACHMENT
          | --interconnect-attachment-region=INTERCONNECT_ATTACHMENT_REGION
          | --vpn-tunnel=VPN_TUNNEL | --vpn-tunnel-region=VPN_TUNNEL_REGION]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) gcloud alpha compute routers update-interface is used to update an
    interface on a Compute Engine router.

POSITIONAL ARGUMENTS
     NAME
        Name of the router to update.

REQUIRED FLAGS
     --interface-name=INTERFACE_NAME
        The name of the interface being updated.

OPTIONAL FLAGS
     --ip-address=IP_ADDRESS
        The link local (IPv4) or ULA (IPv6) address of the router for this
        interface.

     --ip-version=IP_VERSION
        IP version of the interface. Possible values are IPV4 and IPV6.
        Defaults to IPV4. IP_VERSION must be one of:

         IPV4
            Interface with IPv4-based BGP.
         IPV6
            Interface with IPv6-based BGP.

     --mask-length=MASK_LENGTH
        The subnet mask for the IP range of the interface. The interface IP
        address and BGP peer IP address must be selected from the subnet
        defined by this range.

     --region=REGION
        Region of the router to update. 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.

     At most one of these can be specified:

       --interconnect-attachment=INTERCONNECT_ATTACHMENT
          The interconnect attachment of the interface being updated.

       --interconnect-attachment-region=INTERCONNECT_ATTACHMENT_REGION
          Region of the interconnectAttachment to operate on. If not specified
          it will be set to the region of the router. Overrides the default
          compute/region property value for this command invocation.

       --vpn-tunnel=VPN_TUNNEL
          The tunnel of the interface being updated.

       --vpn-tunnel-region=VPN_TUNNEL_REGION
          Region of the vpn tunnel to operate on. If not specified it will be
          set to the region of the router. Overrides the default compute/region
          property value for this command invocation.

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 routers update-interface

        $ gcloud beta compute routers update-interface
