How can I share a subnet in a VPC with another AWS account?

Resolution

Important: A subnet can be shared only across accounts that are in the same AWS Organization.

1. Turn on resource sharing within AWS Organizations using the management account.
2. Create a resource share.
3. Share a subnet from the account that owns the VPC (owner account) to the account that will use the subnet (participant account). The shared subnet automatically appears in the participant account.
