Create a VPC peering connection

To create a VPC peering connection, first create a request to peer with another VPC. To activate the request, the owner of the accepter VPC must accept the request. The following peering connections are supported:

• Between VPCs in the same account and Region

• Between VPCs in the same account and different Regions

• Between VPCs in different accounts and the same Region

• Between VPCs in different accounts and Regions

For an inter-Region VPC peering connection, the request must be made from the Region of the requester VPC, and the request must be accepted from the Region of the accepter VPC. For more information, see Accept or reject a VPC peering connection.

Prerequisites

• Review the limitations for VPC peering connections.

• Ensure that the VPCs do not have overlapping IPv4 CIDR blocks. If they overlap, the status of the VPC peering connection immediately goes to failed. This limitation applies even if the VPCs have unique IPv6 CIDR blocks.
