ec2-replace-route-table-association
Description
Changes the route table associated with a subnet in a VPC.
You can also use this 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 that you want to be the new main route table.
After you execute this action, the subnet uses the routes in the new route table it's associated with. For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.
The short version of this command is ec2reprtbassoc.

For a limited time, you can still use the private key and X.509 certificate instead of your access key ID and secret access key. However, we recommend that you start using your access key ID (-O, --aws-access-key) and secret access key (-W, --aws-secret-key) now, as the private key (-K, --private-key) and X.509 certificate (-C, --cert) won't be supported after the transition period elapses.
