I want to use AWS Resource Access Manager (AWS RAM) to share Amazon Route 53 Resolver rules across multiple virtual private clouds (VPCs) or AWS accounts.
Before you begin, consider the following:
In Account A, create Route 53 Resolver rules to share with other accounts and VPCs.
DNS queries from the VPC now use the outbound endpoint for the shared rule from Account A. AWS RAM manages connectivity between the VPC and the outbound endpoint for the rule from Account A.
