Setting up a peering connection from a third party
I am wondering if you could help out how I set up a peering connection to my demo vpc from a third party. The peering is already set up and I have approved the connection in the console. I need to add the routes to my app -vpc. Do I reference the peering module in my app-vpc file? Do I use the external or just the normal peering module? I am running a bit old versions of the terraform-aws-vpc (v5.6). I am currently just doing this to test but would like to do it in prod eventually. Can I do it the same way we have our mgmt peering like in this example? https://gruntwork.io/guides/networking/how-to-deploy-production-grade-vpc-aws/#deploy_application_vpcs
You can use the [vpc-peering-external](https://github.com/gruntwork-io/terraform-aws-vpc/tree/master/modules/vpc-peering-external) module and I suggest you to have a look at the [vpc-peering-external example](https://github.com/gruntwork-io/terraform-aws-vpc/tree/master/examples/vpc-peering-external).
