# Create a shared Direct Connect gateway attachment in an AWS Cloud WAN core network
Create a shared Direct Connect gateway attachment

The following steps guide you through creating a shared Direct Connect gateway attachment.

**To create a shared Direct Connect gateway attachment**

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

1. Under **Connectivity**, choose **Global Networks**.

1. On the **Global networks** page, choose the global network ID.

1. In the navigation pane, under **Shared by me**, choose **Attachments**.

1. Choose **Create attachment**.

1. Enter a **Name** identifying the attachment.

1. From the **Core network** drop-down list, choose the core network that you want to associate the Direct Connect gateway with.

1. From the **Attachment type** drop-down list choose **Direct Connect gateway attachment**.

1. For the **Edge locations**, choose one of the following:
   + **All** — Choose this option if you want to associate all edge locations in your core network with the Direct Connect gateway. When choosing this option, any new edge locations deployed in a core network policy version are automatically added to the Direct Connect gateway attachment and updated with the Direct Connect gateway. This does not automatically update any edge locations you might remove from the core network policy. 
   + **Specific** — Choose this option if you want to associate only a subset of edge locations from your core network policy with the Direct Connect gateway. When choosing this option, you must manually add new or remove edge locations to the Direct Connect gateway attachment after deploying a core network policy version. A Direct Connect attachment will be attached to the core network edge according to the core network policy edge locations but will associated to the segment based on the segment edge locations.

1. In the** Direct Connect gateway attachment **section, choose the Direct Connect gateway to use for connecting Direct Connect to the Cloud WAN core network. 
**Note**  
A Direct Connect gateway can be used for only one core network, and can't be used for any other Direct Connect gateway type. If the attachment between the Direct Connect gateway and the core network is removed, the gateway becomes available for other Direct Connect association types.

1. Choose **Create attachment**.
