DESCRIPTION
    (ALPHA) gcloud alpha compute networks update is used to update Compute
    Engine networks.

POSITIONAL ARGUMENTS
     NAME
        Name of the network to operate on.

FLAGS
     --async
        Return immediately, without waiting for the operation in progress to
        complete.

     --[no-]enable-ula-internal-ipv6
        Enable/disable ULA internal IPv6 on this network. Enabling this feature
        will assign a /48 from google defined ULA prefix fd20::/20.

        Use --enable-ula-internal-ipv6 to enable and
        --no-enable-ula-internal-ipv6 to disable.

     --internal-ipv6-range=INTERNAL_IPV6_RANGE
        When enabling ULA internal IPv6, caller can optionally specify the /48
        range they want from the google defined ULA prefix fd20::/20.
        ULA_IPV6_RANGE must be a valid /48 ULA IPv6 address and within the
        fd20::/20. Operation will fail if the speficied /48 is already in used
        by another resource. If the field is not speficied, then a /48 range
        will be randomly allocated from fd20::/20 and returned via this field.

     --mtu=MTU
        Maximum transmission unit (MTU) is the size of the largest IP packet
        that can be transmitted on this network. Default value is 1460 bytes.
        The minimum value is 1300 bytes and the maximum value is 8896 bytes.
        The MTU advertised via DHCP to all instances attached to this network.

     --network-firewall-policy-enforcement-order=NETWORK_FIREWALL_POLICY_ENFORCEMENT_ORDER
        The Network Firewall Policy enforcement order of this network. If not
        specified, defaults to AFTER_CLASSIC_FIREWALL.

        NETWORK_FIREWALL_POLICY_ENFORCEMENT_ORDER must be one of:

         AFTER_CLASSIC_FIREWALL
            Network Firewall Policy is enforced after classic firewall.
         BEFORE_CLASSIC_FIREWALL
            Network Firewall Policy is enforced before classic firewall.

     BGP Best Path Selection flags

       --bgp-best-path-selection-mode=BGP_BEST_PATH_SELECTION_MODE
          The BGP best selection algorithm to be employed. MODE can be LEGACY
          or STANDARD. BGP_BEST_PATH_SELECTION_MODE must be one of:

           LEGACY
              Dynamic routes are ranked based on MED BGP attribute. When global
              routing is enabled, MED of the routes received from other regions
              is original MED plus region-to-region cost.
           STANDARD
              Dynamic routes are ranked based on AS Path, Origin, Neighbor ASN
              and MED BGP attributes. When global routing is enabled,
              region-to-region cost is used as a tiebreaker. This mode offers
              customizations to fine-tune BGP best path routing with additional
              knobs like --bgp-bps-always-compare-med and
              --bgp-bps-inter-region-cost

       --[no-]bgp-bps-always-compare-med
          Enables/disables the comparison of MED across routes with different
          NeighborAsn. This value can only be set if the
          --bgp-best-path-selection-mode is STANDARD. Use
          --bgp-bps-always-compare-med to enable and
          --no-bgp-bps-always-compare-med to disable.

       --bgp-bps-inter-region-cost=BGP_BPS_INTER_REGION_COST
          Allows to define preferred approach for handling inter-region cost in
          the selection process. This value can only be set if the
          --bgp-best-path-selection-mode is STANDARD. BGP_BPS_INTER_REGION_COST
          must be one of:

           ADD_COST_TO_MED
              Adds inter-region cost to the MED before comparing MED value.
              When multiple routes have the same value after the
              Add-cost-to-med comparison, the route selection continues and
              prefers the route with lowest cost.
           DEFAULT
              MED is compared as originally received from peers. Cost is
              evaluated as a next step when MED is the same.

     At most one of these can be specified:

       --bgp-routing-mode=MODE
          The target BGP routing mode for this network. MODE must be one of:

           global
              Cloud Routers in this network advertise subnetworks from all
              regions to their BGP peers, and program instances in all regions
              with the router's best learned BGP routes.
           regional
              Cloud Routers in this network advertise subnetworks from their
              local region only to their BGP peers, and program instances in
              their local region only with the router's best learned BGP
              routes.

       --switch-to-custom-subnet-mode
          Switch to custom subnet mode. This action cannot be undone.

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 networks update

        $ gcloud beta compute networks update
