When configuring a Virtual Private Cloud (VPC) peering connection between my VPC and a VPC associated with another AWS account, I receive the error "The connection failed due to incorrect VPC-ID, Account ID, or overlapping CIDR range." How do I resolve this?

This error occurs when the VPC ID or the Account ID of the peering VPC is incorrect or if the CIDR ranges overlap.

To resolve peering connection errors between VPCs, follow these steps:

  1. Verify that the VPC ID and the Account ID of the peering VPC are correct. You can't create a VPC peering connection with a VPC in another AWS account if the VPC ID and the Account ID of the peering VPC are incorrect. For more information, see Creating a VPC Peering Connection with a VPC in Another AWS Account.
  2. Verify that the CIDR ranges of the two VPCs do not overlap. For more information, see Overlapping CIDR Blocks.
