Associating Subnets with a Route Table¶

Function¶

This API is used to associate a subnet with a route table.

If a subnet has already been associated with route table A, you can associate the subnet with route table B directly without disassociating it from route table A first.

URI¶

POST /v1/{project_id}/routetables/{routetable_id}/action

Table 1 describes the parameters.

**Table 1** Parameter description¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.
routetable_id	Yes	String	Specifies the route table ID, which uniquely identifies a route table.

Request Parameters¶

**Table 2** Request parameter¶
Parameter	Mandatory	Type	Description
routetable	Yes	routetable object	Specifies the route table. For details, see Table 3.

**Table 3** Description of the **routetable** field¶
Parameter	Mandatory	Type	Description
subnets	Yes	subnet object	Specifies the subnets associated with the route table. Only subnets (specified by network_id) in the VPC that the route table belongs to can be associated with the route table.

**Table 4** Description of the **subnet** field¶
Parameter	Mandatory	Type	Description
associate	No	Array of strings	Specifies a list of IDs of the subnets to be associated with the route table.
disassociate	No	Array of strings	Specifies a list of IDs of the subnets to be disassociated from the route table.

Example Request¶

    "routetable": {
        "subnets": {
            "associate": [
                "1a8b8c98-3976-401b-a735-8b058109268c"
            ]
        }
    }
}

Response Parameters¶

**Table 5** Response parameter¶
Parameter	Type	Description
routetable	routetable object	Specifies the route table. For details, see Table 6.

**Table 6** Description of the **routetable** field¶
Parameter	Type	Description
id	String	Specifies the route table ID, which uniquely identifies the route table. The value must be in standard UUID format.
name	String	Specifies the route table name. The value can contain no more than 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).
default	Boolean	Specifies whether the route table is the default one. The value can be true (default route table) or false (custom route table).
routes	Array of route objects	Specifies the route list. For details, see Table 7. Each route table can have a maximum of 200 routes.
subnets	Array of subnet objects	Specifies the subnets associated with the route table. For details, see Table 8. Only subnets in the VPC to which the route table belongs can be associated with the route table.
tenant_id	String	Specifies the project ID.
vpc_id	String	Specifies the ID of the VPC associated with the route table.
description	String	Provides supplementary information about the route table. The value can contain no more than 255 characters and cannot contain angle brackets (< or >).

**Table 7** Description of the **route** field¶
Parameter	Type	Description
type	String	Specifies the route type. Values: ecs (ECS) eni (NIC) vip (Virtual IP address) nat (NAT gateway) peering (VPC peering connection) vpn (VPN) dc (Direct Connect connection) egw: VPC endpoint. This route type is not supported. er: enterprise router subeni: supplementary network interface. This type of route cannot be created or updated by users. local: reserved CIDR block. The destination CIDR block of the route configured cannot overlap with that defined by local.
destination	String	Specifies the destination CIDR block of a route. Constraints: The value must be in valid IPv4 or IPv6 CIDR formats.
nexthop	String	Specifies the ID of the next hop in the route. Values: When type is ecs, the value is an ECS ID. When type is eni, the value is an extension NIC ID. When type is vip, the value is a virtual IP address. When type is nat, the value a NAT gateway ID. When type is peering, the value is a VPC peering connection ID. When type is vpn, the value is a VPN ID. When type is dc, the value is a Direct Connect connection ID. When type is set to egw, the value is a VPC endpoint ID. When type is set to er, the value is the ID of an enterprise router. When type is set to subeni, the value is the ID of a supplementary network interface.
description	String	Provides supplementary information about the route. The value can contain up to 255 characters and cannot contain angle brackets (< or >).

**Table 8** Description of the **subnet** field¶
Parameter	Type	Description
id	String	Specifies the ID of the subnet associated with the route table.
