NAME: gcloud alpha compute routers add-interface - add an interface to a Compute Engine router
SYNOPSIS: gcloud alpha compute routers add-interface NAME --interface-name=INTERFACE_NAME (--interconnect-attachment=INTERCONNECT_ATTACHMENT --interconnect-attachment-region=INTERCONNECT_ATTACHMENT_REGION | --subnetwork=SUBNETWORK --subnetwork-region=SUBNETWORK_REGION | --vpn-tunnel=VPN_TUNNEL --vpn-tunnel-region=VPN_TUNNEL_REGION) [--ip-address=IP_ADDRESS] [--ip-version=IP_VERSION] [--mask-length=MASK_LENGTH] [--redundant-interface=REDUNDANT_INTERFACE] [--region=REGION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) gcloud alpha 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 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:
