Create a shared peering in an AWS Cloud WAN global network

The following steps guide you through creating a shared peering in your core network.

Important

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

• ec2:CreateTransitGatewayPolicyTable

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

4. In the navigation pane, under Shared by me, choose Peerings.

5. Choose Create peering.

6. Enter a name to identify the attachment.

7. From the Core network dropdown list, choose the core network that is shared with you and that is where you want to create the peering.
