-- | Changes the route table associated with a given subnet in a VPC. After the
-- operation completes, the subnet uses the routes in the new route table it's
-- associated with. For more information about route tables, see <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Route_Tables.html Route Tables> in
-- the /Amazon Virtual Private Cloud User Guide/.
--
-- You can also use ReplaceRouteTableAssociation to change which table is the
-- main route table in the VPC. You just specify the main route table's
-- association ID and the route table to be the new main route table.
