NAME

Name of the router to create.

--network=NETWORK

The network for this router

--advertisement-mode=MODE

The new advertisement mode for this router. MODE must be one of:

CUSTOM

Custom (user-configured) BGP advertisements.

DEFAULT

Default (Google-managed) BGP advertisements.

--asn=ASN

The optional BGP autonomous system number (ASN) for this router. Must be a 16-bit or 32-bit private ASN as defined in https://tools.ietf.org/html/rfc6996, for example --asn=64512.

--async

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

--bgp-identifier-range=BGP_IDENTIFIER_RANGE

The range of valid BGP Identifiers for this Router. Must be a link-local IPv4 range from 169.254.0.0/16, of size at least /30, even if the BGP sessions are over IPv6. It must not overlap with any IPv4 BGP session ranges. This is commonly called "router ID" by other vendors.

--description=DESCRIPTION

An optional description of this router.

--encrypted-interconnect-router

Indicates if a router is dedicated for use with encrypted interconnect attachments (VLAN attachments).

--keepalive-interval=KEEPALIVE_INTERVAL

The interval between BGP keepalive messages that are sent to the peer. If set, this value must be between 20 and 60 seconds. The default is 20 seconds. See $ gcloud topic datetimes for information on duration formats.

BGP systems exchange keepalive messages to determine whether a link or host has failed or is no longer available. Hold time is the length of time in seconds that the BGP session is considered operational without any activity. After the hold time expires, the session is dropped.

Hold time is three times the interval at which keepalive messages are sent, and the hold time is the maximum number of seconds allowed to elapse between successive keepalive messages that BGP receives from a peer. BGP will use the smaller of either the local hold time value or the peer's hold time value as the hold time for the BGP connection between the two peers.

--region=REGION

Region of the router to create. 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.

--set-advertisement-groups=[GROUP,…]

The list of pre-defined groups of IP ranges to dynamically advertise on this router. This list can only be specified in custom advertisement mode.

GROUP must be (only one value is supported):

ALL_SUBNETS

Automatically advertise all available subnets. This excludes any routes learned for subnets that use VPC Network Peering.

--set-advertisement-ranges=[CIDR_RANGE=DESC,…]

The list of individual IP ranges, in CIDR format, to dynamically advertise on this router. Each IP range can (optionally) be given a text description DESC. For example, to advertise a specific range, use --set-advertisement-ranges=192.168.10.0/24. To store a description with the range, use --set-advertisement-ranges=192.168.10.0/24=my-networks. This list can only be specified in custom advertisement mode.
