NAME: gcloud compute routers update-interface - update an interface on a Compute 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 | --vpn-tunnel=VPN_TUNNEL | --vpn-tunnel-region=VPN_TUNNEL_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.
