Here’s a little oddity with AWS Route Tables within Terraform, if you want to remove all of the routes in a route table, you can’t just delete or comment them out, otherwise it treats them as if nothing has changed.<\/p>\n\n\n\n
See the below example, you comment\/remove the routes, then in its place add a blank set.<\/p>\n\n\n\n
