DESCRIPTION
    (BETA) gcloud beta compute routers add-interface is used to add an
    interface to 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 added.

     Exactly one of these must be specified:

       Interconnect Attachment

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

       --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.

       Subnetwork

       --subnetwork=SUBNETWORK
          The subnetwork of the interface being added.

       --subnetwork-region=SUBNETWORK_REGION
          Region of the subnetwork 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=VPN_TUNNEL
          The tunnel of the interface being added.

       --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.

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.

     --redundant-interface=REDUNDANT_INTERFACE
        The interface that is redundant to the current interface.

     --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.

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 beta and might change without notice. These
    variants are also available:

        $ gcloud compute routers add-interface

        $ gcloud alpha compute routers add-interface
