-- | 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 about route tables, see Route Tables
-- in the Amazon Virtual Private Cloud User Guide.
