Create a peering in an AWS Cloud WAN core network

Create a transit gateway peering.

Important

Before creating a peering, make sure that the account you use to create the peering has the following permissions:

  • ec2:CreateTransitGatewayPolicyTable

  • ec2:AcceptTransistGatewayPeering

  • ec2:AssociateTransitGatewayPolicyTable

To create a peering

  1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

  2. Under Connectivity, choose Global Networks.

  3. On the Global networks page, choose the global network ID.

  4. Under Core network in the navigation pane, choose Peerings.

  5. Choose Create peering.

  6. (Optional) Enter a name identifying the peering.

  7. From the Edge location dropdown list, choose the edge location where the peering is located.

  8. From the Transit gateway dropdown list, choose a transit gateway to be used for the peering.

    Note

    The core ASN and the transit gateway ASN must be unique. ASNs must be unique for peerings to succeed.

  9. Choose one of the following Associate policy table options:

    • New — Creates a new policy routing table.

    • Existing — Allows you to associate this peering with an existing policy table. If you choose this option, you'll be prompted to choose an existing Transit gateway policy table to associate with the peering. For information on creating a transit gateway policy table, see Transit Gateway policy tables in the AWS Transit Gateway Guide.

  10. (Optional) If the transit gateway is not registered in your global network, choose Register the specific transit gateway to the global network to simultaneously register the transit gateway to the global network. If your transit gateway is already registered, this option does not display.

  11. (Optional) In the Tags section, add Key and Value tags to help identify this resource. You can add multiple tags by choosing Add tag, or remove any tag by choosing Remove tag.

  12. Choose Create peering.

    The Create peering progress displays the current status of the peering deployment. When deployment is complete, the State of the peering on the Peerings page displays Available. You can then use this peering to create a transit gateway route table attachment. See Transit gateway route table attachments in AWS Cloud WAN
