Create a VPC peering connection

To create a VPC peering connection, first create a request to peer with another VPC. You can request a VPC peering connection with another VPC in your account, or with a VPC in a different AWS account. For an inter-Region VPC peering connection where the VPCs are in different Regions, the request must be made from the Region of the requester VPC.

To activate the request, the owner of the accepter VPC must accept the request. For an inter-Region VPC peering connection, the request must be accepted in the Region of the accepter VPC. For more information, see Accept a VPC peering connection. For more information about the Pending acceptance peering connection status, see VPC peering connection lifecycle.

Prerequisites

• Review the limitations and rules for VPC peering connections.

• Ensure that your 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.

Create with VPCs in the same account and Region

To create a VPC peering connection with VPCs in the same account and Region

1. Open the Amazon VPC console at https://console.aws.amazon.com/vpc/.

2. In the navigation pane, choose Peering connections.

3. Choose Create peering connection.

4. Configure the following information, and choose Create peering connection when you are done:
