GatewayConnection (schema)

Name	Description	Type	Notes
_create_time	Timestamp of resource creation	EpochMsTimestamp	Readonly Sortable
_create_user	ID of the user who created this resource	string	Readonly
_last_modified_time	Timestamp of last modification	EpochMsTimestamp	Readonly Sortable
_last_modified_user	ID of the user who last modified this resource	string	Readonly
_links	References related to this resource The server will populate this field when returing the resource. Ignored on PUT and POST.	array of ResourceLink	Readonly
_protection	Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true. UNKNOWN - the _protection field could not be determined for this entity.	string	Readonly
_revision	Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected.	int
_schema	Schema for this resource	string	Readonly
_self	Link to this resource	SelfResourceLink	Readonly
_system_owned	Indicates system owned resource	boolean	Readonly
advertise_outbound_networks	List of advertised external IP blocks. List of advertised prefixes through external ip blocks configuration. List of private prefixes can be allowed by setting allow_private to true in ProviderAdvertiseOutBoundNetworks.	ProviderAdvertiseOutBoundNetworks
advertise_outbound_route_filters	Outbound advertise route filters Array of path of a prefixlist object that will have Transit gateway to tier-0 gateway advertise route filter.	array of string	Maximum items: 1
aggregate_routes	Aggregate routes Configure aggregate TGW_PREFIXES routes on Tier-0 gateway for prefixes owned by TGW gateway. If not specified then in-use prefixes are configured as TGW_PREFIXES routes on Tier-0 gateway.	array of IPv4CIDRBlock
children	Subtree for this type within policy tree Subtree for this type within policy tree containing nested elements. Note that this type is applicable to be used in Hierarchical API only.	array of ChildPolicyConfigResource Children are not allowed for this type
description	Description of this resource	string	Maximum length: 1024 Sortable
display_name	Identifier to use when displaying entity in logs or GUI Defaults to ID if not set	string	Maximum length: 255 Sortable
id	Unique identifier of this resource	string	Sortable
inbound_remote_networks	Inbound remote network routes for TGW List of inbound remote network routes for transit gateways. Default route [0.0.0.0/0] will be assumed if remote networks are not configured. For multiple attachments on TGW, only one gateway connection can support default route. Other gateway connections must have networks configured.	array of IPv4CIDRBlock
marked_for_delete	Indicates whether the intent object is marked for deletion Intent objects are not directly deleted from the system when a delete is invoked on them. They are marked for deletion and only when all the realized entities for that intent object get deleted, the intent object is deleted. Objects that are marked for deletion are not returned in GET call. One can use the search API to get these objects.	boolean	Readonly Default: "False"
nat_config	NAT config for transit gateway. Provider managed NAT configs for transit gateway.	ProviderNatConfig
origin_site_id	A unique identifier assigned by the system for knowing which site owns an object This is a UUID generated by the system for knowing which site owns an object. This is used in NSX+.	string	Readonly
overridden	Indicates whether this object is the overridden intent object Global intent objects cannot be modified locally by the user. However, certain global intent objects can be overridden locally by use of this property. In such cases, the overridden local values take precedence over the globally defined values for the properties.	boolean	Readonly Default: "False"
owner_id	A unique identifier assigned by the system for the ownership of an object This is a UUID generated by the system for knowing who owns this object. This is used in NSX+.	string	Readonly
parent_path	Path of its parent Path of its parent	string	Readonly
path	Absolute path of this object Absolute path of this object	string	Readonly
realization_id	A unique identifier assigned by the system for realizing intent This is a UUID generated by the system for realizing the entity object. In most cases this should be same as 'unique_id' of the entity. However, in some cases this can be different because of entities have migrated their unique identifier to NSX Policy intent objects later in the timeline and did not use unique_id for realization. Realization id is helpful for users to debug data path to correlate the configuration with corresponding intent.	string	Readonly
relative_path	Relative path of this object Path relative from its parent	string	Readonly
remote_path	Path of the object on the remote end. This path is populated only in case of multi-site scenario. Currently it is supported only for LM objects. When LM is onboarded to multi-site platform like NAPP or GM, remote_path will be set to the globally unique path across multi-site topology . It is generated based on local site-name and uses /org tree namespace. Note: It is populated only for LM objects. Not supported on the GM.	string	Readonly
resource_type	Must be set to the value GatewayConnection	string
tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30
tier0_path	Tier-0 path Tier-0 gateway object path	string	Required
unique_id	A unique identifier assigned by the system This is a UUID generated by the GM/LM to uniquely identify entities in a federated environment. For entities that are stretched across multiple sites, the same ID will be used on all the stretched sites.	string	Readonly

Example Request:

PUT https://<policy-mgr>/policy/api/v1/infra/gateway-connections/tenant-1 { "resource_type": "GatewayConnection", "id": "tenant-1", "display_name": "tenant-1", "description": "Gateway connection", "tier0_path" : "/infra/tier-0s/gateway", "aggregate_routes": ["14.1.1.1/24", "16.1.1.2/24"] "advertise_outbound_route_filters": ["/infra/routing-config/prefix-lists/pl-1"], "inbound_remote_networks:["196.1.1.0/24"], "advertise_outbound_networks":{ "allow_external_blocks" : ["/infra/ip-blocks/nat-ip-blocks","/infra/ip-blocks/nat-ip-blocks-2"], "allow_private" : false }, "nat_config" : { "enable_snat" : true, "ip_block" : "/infra/ip-blocks/nat-ip-blocks" } }
