CreateRouteEntry-Virtual Private Cloud(VPC)-阿里云帮助中心

Creates a custom route entry on a vRouter or a Virtual Border Router (VBR).

Operation description

The CreateRouteEntry operation is asynchronous. After you call this operation, the system returns an instance ID, but custom route entry is not yet added and the background task is still running. You can call DescribeRouteEntryList to query the status of custom route entry:
- If custom route entry is in the Creating state, custom route entry is being added.
- If custom route entry is in the Created state, custom route entry is added.
The CreateRouteEntry operation does not support adding custom route entries concurrently in the same VPC or on the same VBR.
The CreateRouteEntry operation may return the TaskConflict error code in concurrent scenarios. Retry the operation as needed.

When you call this operation to add a custom route entry to the route table of a vRouter, take note of the following items:

Note

When the added route is a prefix list route, the route quota is calculated based on whether the sum of the number of existing routes and the maximum number of route entries for the prefix list route exceeds the route quota limit.

A route table can contain at most 200 custom route entries.
The destination CIDR block (DestinationCidrBlock) of a custom route entry cannot be the same as the CIDR block of a vSwitch in the VPC. The destination CIDR block can contain the CIDR block of the vSwitch, but cannot be contained by the CIDR block of the vSwitch.
The destination CIDR block (DestinationCidrBlock) of a custom route entry can be configured as a more specific CIDR block than the system route CIDR block 100.64.0.0/10 for cloud services, but cannot be the same as the system route CIDR block.
Important The system route whose destination CIDR block is 100.64.0.0/10 is used for communication between cloud services in the VPC. Proceed with caution when you configure a more specific route. An incorrect configuration may cause cloud services to become inaccessible.
Route entries in the same route table cannot have the same destination CIDR block (DestinationCidrBlock).
If the specified destination CIDR block (DestinationCidrBlock) is an IP address, it is treated as a /32 CIDR block.
You can specify the same next hop (NextHopId) for more than one custom route entry.
The next hop (NextHopId) of a custom route entry must be in the same VPC as the route table.
You can configure equal-cost multi-path (ECMP) routing by using the NextHopList parameter settings:
- When you add a regular (non-ECMP) custom route, you must specify the DestinationCidrBlock, NextHopType, and NextHopId parameters, and you cannot specify the NextHopList parameter.
- When you add an ECMP route, you must specify the DestinationCidrBlock and NextHopList parameters, and you cannot specify the NextHopType and NextHopId parameters.

When you call this operation to add a custom route entry to the route table of a VBR, take note of the following items:

A route table can contain at most 200 custom route entries.
The NextHopList parameter is not supported.
The destination CIDR block (DestinationCidrBlock) of a custom route entry can be configured as a more specific CIDR block than the system route CIDR block 100.64.0.0/10 for cloud services, but cannot be the same as the system route CIDR block.
Important The system route whose destination CIDR block is 100.64.0.0/10 is used for communication between cloud services in the VPC. Proceed with caution when you configure a more specific route. An incorrect configuration may cause cloud services to become inaccessible.
Route entries in the same route table cannot have the same destination CIDR block (DestinationCidrBlock).
If the specified destination CIDR block (DestinationCidrBlock) is an IP address, it is treated as a /32 CIDR block.
You can specify the same next hop (NextHopId) for more than one custom route entry.
The next hop (NextHopId) of a custom route entry must be a vRouter interface associated with the VBR.
You can add a route entry to a VBR only when the VBR is in the Active state, the associated Express Connect circuit is in the Enabled state, and the VBR is not locked due to an overdue payment.
Only regular (non-ECMP) routes can be added. You must specify the DestinationCidrBlock, NextHopType, and NextHopId parameters, and you cannot specify the NextHopList parameter.

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 supports 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.
