ec2-associate-route-table

Description

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 if you want to disassociate the route table from the subnet later. A route table can be associated with multiple subnets.

For more information about route tables, go to Route Tables in the Amazon Virtual Private Cloud User Guide.

The short version of this command is ec2assocrtb.
