Preview fields auto-generated during router create and update operations. Calling this method does NOT create or update the router.

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/compute
  • https://www.googleapis.com/auth/compute.readonly

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: compute1 --scope <scope> routers preview ...

Required Scalar Arguments

  • <project> (string)
    • Project ID for this request.
  • <region> (string)
    • Name of the region for this request.
  • <router> (string)
    • Name of the Router resource to query.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

Router:
  bgp:
    advertise-mode: string
    advertised-groups: [string]
    asn: integer
    keepalive-interval: integer
  creation-timestamp: string
  description: string
  encrypted-interconnect-router: boolean
  id: string
  kind: string
  name: string
  network: string
  region: string
  self-link: string

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r .bgp advertise-mode=sit
    • User-specified flag to indicate which mode to use for advertisement. The options are DEFAULT or CUSTOM.
  • advertised-groups=rebum.
    • User-specified list of prefix groups to advertise in custom mode. This field can only be populated if advertise_mode is CUSTOM and is advertised to all peers of the router. These groups will be advertised in addition to any specified prefixes. Leave this field blank to advertise no custom groups.
    • Each invocation of this argument appends the given value to the array.
  • asn=100
    • Local BGP Autonomous System Number (ASN). Must be an RFC6996 private ASN, either 16-bit or 32-bit. The value will be fixed for this router resource. All VPN tunnels that link to this router will have the same local ASN.

  • keepalive-interval=81

    • The interval in seconds between BGP keepalive messages that are sent to the peer. 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. If set, this value must be between 20 and 60. The default is 20.

  • .. creation-timestamp=dolore

    • [Output Only] Creation timestamp in RFC3339 text format.
  • description=no
    • An optional description of this resource. Provide this property when you create the resource.
  • encrypted-interconnect-router=false
    • Indicates if a router is dedicated for use with encrypted VLAN attachments (interconnectAttachments).
  • id=ea
    • [Output Only] The unique identifier for the resource. This identifier is defined by the server.
  • kind=dolor
    • [Output Only] Type of resource. Always compute#router for routers.
  • name=eirmod
    • Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
  • network=vero
    • URI of the network to which this router belongs.
  • region=dolore
    • [Output Only] URI of the region where the router resides. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.
  • self-link=sadipscing
    • [Output Only] Server-defined URL for the resource.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

  • -p $-xgafv=string

    • V1 error format.

  • -p access-token=string

    • OAuth access token.

  • -p alt=string
