It represents a connection between a hub and various network resources such as VPN tunnels, VLAN attachments, or router appliance instances. Spokes simplify the management of large-scale network topologies by centralizing connectivity through a hub-and-spoke model, improving visibility and control over hybrid and multi-cloud networks. ``` gcp.networkconnectivity_spoke ``` ## Fields | Title | ID | Type | Data Type | Description | | --------------------------------- | ---- | ------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------- | | _key | core | string | | ancestors | core | array | | create_time | core | timestamp | Output only. The time the spoke was created. | | datadog_display_name | core | string | | description | core | string | Optional. An optional description of the spoke. | | etag | core | string | Optional. This checksum is computed by the server based on the value of other fields, and may be sent on update and delete requests to ensure the client has an up-to-date value before proceeding. | | field_paths_pending_update | core | array | Optional. The list of fields waiting for hub administrator's approval. | | group | core | string | Optional. The name of the group that this spoke is associated with. | | hub | core | string | Immutable. The name of the hub that this spoke is attached to. | | labels | core | array | Optional labels in key-value pair format. For more information about labels, see [Requirements for labels](https://cloud.google.com/resource-manager/docs/creating-managing-labels#requirements). | | linked_interconnect_attachments | core | json | Optional. VLAN attachments that are associated with the spoke. | | linked_producer_vpc_network | core | json | Optional. The linked producer VPC that is associated with the spoke. | | linked_router_appliance_instances | core | json | Optional. Router appliance instances that are associated with the spoke. | | linked_vpc_network | core | json | Optional. VPC network that is associated with the spoke. | | linked_vpn_tunnels | core | json | Optional. VPN tunnels that are associated with the spoke. | | name | core | string | Immutable. The name of the spoke. Spoke names must be unique. They use the following form: `projects/{project_number}/locations/{region}/spokes/{spoke_id}` | | organization_id | core | string | | parent | core | string | | project_id | core | string | | project_number | core | string | | reasons | core | json | Output only. The reasons for current state of the spoke. | | region_id | core | string | | resource_name | core | string | | spoke_type | core | string | Output only. The type of resource associated with the spoke. | | state | core | string | Output only. The current lifecycle state of this spoke. | | tags | core | hstore_csv | | unique_id | core | string | Output only. The Google-generated UUID for the spoke. This value is unique across all spoke resources. If a spoke is deleted and another with the same name is created, the new spoke is assigned a different `unique_id`. | | update_time | core | timestamp | Output only. The time the spoke was last updated. | | zone_id | core | string |
