Queries the aggregate routes in the route table of an Enterprise Edition transit router.

Operation description

You can specify the TransitRouteTableId and TransitRouteTableAggregationCidr parameters to query a specific aggregate route. If you specify only the TransitRouteTableId parameter, all aggregate routes in the route table of the Enterprise Edition transit router are queried by default.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that support authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
TransitRouteTableId	string	Yes	The ID of the route table of the Enterprise Edition transit router.	vtb-6ehgc262hr170qgyc****
TransitRouteTableAggregationCidr	string	No	The destination CIDR block of the aggregate route.	192.168.10.0/24
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. Generate a token from your client to ensure that the token is unique among different requests. The token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the request as the ClientToken. The RequestId is different for each request.	02fb3da4-130e-11e9-8e44-001****
MaxResults	integer	No	The number of entries to return on each page. Default value: 20.	20
NextToken	string	No	The pagination token that is used in the next request to retrieve a new page of results. Valid values: You do not need to specify this parameter for the first request. You must specify the token that is obtained from the previous query as the value of NextToken.	FFmyTO70tTpLG6I3FmYAXGKPd****

Response parameters

Parameter	Type	Description	Example
	object	The response that is returned.
Data	array<object>	A list of aggregate routes.
	object	The information about the aggregate route.
Name	string	The name of the aggregate route.	nametest
TransitRouteTableAggregationCidr	string	The destination CIDR block of the aggregate route.	192.168.10.0/24
Scope	string	The scope of the aggregate route. The value is set to VPC. This indicates that the aggregate route is advertised to all VPCs that are associated with the route table of the Enterprise Edition transit router and have route synchronization enabled.	VPC
RouteType	string	The type of the aggregate route. The value is set to Static. This indicates that the route is a static route. After the aggregate route is advertised to a VPC, it becomes a custom route entry by default.	Static
Description	string	The description of the aggregate route.	desctest
TrRouteTableId	string	The ID of the route table of the Enterprise Edition transit router.	vtb-6ehgc262hr170qgyc****
Status	string	The advertising status of the aggregate route. AllConfigured: The aggregate route is advertised to all VPCs. Configuring: The aggregate route is being advertised. ConfigFailed: The aggregate route failed to be advertised. PartialConfigured: The aggregate route is advertised to some VPCs. Deleting: The aggregate route is being deleted.	AllConfigured
ScopeList	array	The list of scopes of the aggregate route. Note You must specify at least one of the Scope and ScopeList properties. We recommend that you specify ScopeList. The elements in ScopeList cannot be the same as the value of Scope.
	string	The list of scopes of the aggregate route. Valid values: VPC: The aggregate route is advertised to all VPCs that are associated with the route table of the Enterprise Edition transit router and have route synchronization enabled. VBR: The aggregate route is advertised to all VBRs that are attached to the Enterprise Edition transit router. Peer: The aggregate route is advertised to transit routers that have an inter-region connection with the Enterprise Edition transit router. VPN: The aggregate route is advertised to all VPN connections that are attached to the Enterprise Edition transit router. ECR: The aggregate route is advertised to all ECR instances that are attached to the Enterprise Edition transit router.	VPC
Count	integer	The number of entries returned on each page.	20
NextToken	string	A pagination token. It can be used in the next request to retrieve a new page of results. Valid values: If NextToken is empty, no next page exists. If a value is returned for NextToken, the value is the token that determines the start point of the next query.	FFmyTO70tTpLG6I3FmYAXGKPd****
Total	integer	The total number of entries.	1
RequestId	string	The request ID.	0C2EE7A8-74D4-4081-8236-CEBDE3BBCF50
