AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Associates a subnet with a route table. The subnet and route table must be in the same VPC. This association causes traffic originating from the subnet to be routed according to the routes in the route table. The action returns an association ID, which you need in order to disassociate the route table from the subnet later. A route table can be associated with multiple subnets.

For more information, see Route Tables in the Amazon Virtual Private Cloud User Guide.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to AssociateRouteTableAsync.
