TransitGatewayPeeringAttachment

The TransitGatewayPeeringAttachment resource lets you manage AWS EC2 Transit Gateway Peering Attachments. This resource facilitates the connection between two transit gateways, allowing for the exchange of traffic between their respective networks.

Minimal Example

Create a basic Transit Gateway Peering Attachment with required properties and some optional tags.

import AWS from "alchemy/aws/control";

const peeringAttachment = await AWS.EC2.TransitGatewayPeeringAttachment("myPeeringAttachment", {
  TransitGatewayId: "tgw-0123456789abcdef0",
  PeerTransitGatewayId: "tgw-0123456789abcdef1",
  PeerAccountId: "123456789012",
  PeerRegion: "us-west-2",
  Tags: [
    {
      Key: "Name",
      Value: "MyTransitGatewayPeering"
    }
  ]
});

Advanced Configuration

Configure the peering attachment with the option to adopt an existing resource.

const advancedPeeringAttachment = await AWS.EC2.TransitGatewayPeeringAttachment("advancedPeeringAttachment", {
  TransitGatewayId: "tgw-0123456789abcdef0",
  PeerTransitGatewayId: "tgw-0123456789abcdef1",
  PeerAccountId: "123456789012",
  PeerRegion: "us-west-2",
  Tags: [
    {
      Key: "Environment",
      Value: "Production"
    }
  ],
  adopt: true // Adopt existing resource instead of failing if it exists
});

Distinct Use Case: Cross-Region Connectivity

Establish a peering attachment between transit gateways in different AWS regions.

const crossRegionPeeringAttachment = await AWS.EC2.TransitGatewayPeeringAttachment("crossRegionPeering", {
  TransitGatewayId: "tgw-0123456789abcdef0",
  PeerTransitGatewayId: "tgw-0123456789abcdef1",
  PeerAccountId: "123456789012",
  PeerRegion: "eu-central-1",
  Tags: [
    {
      Key: "Name",
      Value: "CrossRegionPeering"
    }
  ]
});
