Add an AWS Cloud WAN Connect peer to a core network

You can create a either a GRE Connect peer or a Tunnel-less Connect peer for an existing Connect attachment using either the AWS Cloud WAN console or the command line/API.

Add a GRE Connect peer using the console

The following steps add a GRE Connect peer using the console.

To add a Connect peer using the console

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 Attachments.

5. Choose an attachment with a resource type of Connect.

   The Details tab displays the Connect protocol. Make sure to choose a Connect attachment where the Connect protocol is GRE.

6. Choose the Connect peers tab.

7. Choose Create Connect peer.

8. Enter a Name to identify the Connect peer.

9. (Optional) For the Core network GRE address, enter the GRE outer IP address for the core network edge. By default, the first available address from the Inside CIDR block is used.

10. For the Peer GRE address, enter the GRE outer IP address for the Core Network Edge. By default, the first available address from the Inside CIDR block is used.

11. For BGP Inside CIDR blocks IPv4, enter the range of inside IPv4 addresses used for BGP peering. Use a /29 CIDR block from the 169.254.0.0/16 range.

12. (Optional) For BGP Inside CIDR blocks IPv6, enter the range of inside IPv6 addresses used for BGP peering. Use a /125 CIDR block from the fd00::/8 range.

13. For Peer ASN, specify the Border Gateway Protocol (BGP) Autonomous System Number (ASN) for the appliance. You can use an existing ASN that's assigned to your network. If you do not have one, you can use any ASN in the 1-4294967294 range.

    The default is the same ASN as the core network edge. If you configure the Peer ASN to be different than the core network edge ASN (eBGP), you must configure ebgp-multihop with a time-to-live (TTL) value of 2.

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

15. Choose Create Connect peer.

Add a Tunnel-less Connect peer using the console

The following steps add a Tunnel-less Connect peer using the console.

To add a Tunnel-less Connect peer using the console

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 Attachments.

5. Choose an attachment with a resource type of Connect.

   The Details tab displays the Connect protocol. Make sure to choose a Connect attachment where the Connect protocol is NO_ENCAP.

6. Choose the Connect peers tab.

7. Choose Create Connect peer.

8. Enter a Name to identify the Tunnel-less Connect peer.

9. For the Peer BGP address, enter the appliance's IPv4 address.

   Note

   BGP peering primarily uses IPv4 addresses, but it does support IPv6 addres exchange through MP-BGP. To establsih BGP sessions for IPv6 Unicast, you must have IPv4 Unicast addressing.

10. For the Peer ASN, specify the BGP ASN for the appliance.

    You can use an existing ASN that's assigned to your network. If you do not have one, you can use any ASN in the 1-4294967294 range. The default is the same ASN as the core network edge. If you configure the Peer ASN to be different from the core network edge ASN (eBGP), you must configure ebgp-multihop with a time-to-live (TTL) value of 2.

11. For Subnet, choose the subnet of the appliance.

    Note

    We recommend you run your appliance in the same subnet as your transport VPC attachment.

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

13. Choose Create Connect peer.

Add a Connect peer using the command line or API

Use the command line or API to create an AWS Cloud WAN Connect peer.

To create a Connect peer using the command line or API

• Use create-connect-peer. See create-connect-peer.
