        Engine router

SYNOPSIS
    gcloud 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

        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    gcloud 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
