Create a Connect peer using Amazon VPC Transit Gateways - Amazon VPC

Create a Connect peer using Amazon VPC Transit Gateways

You can create a Connect peer (GRE tunnel) for an existing Connect attachment. Before you begin, ensure that you have configured a transit gateway CIDR block. You can configure a transit gateway CIDR block when you create or modify a transit gateway.

When you create the Connect peer, you must specify the GRE outer IP address on the appliance side of the Connect peer.

To create a Connect peer using the console

  1. Open the Amazon VPC console at https://console.aws.amazon.com/vpc/.

  2. In the navigation pane, choose Transit gateway attachments.

  3. Select the Connect attachment, and choose Actions, Create connect peer.

  4. (Optional) For Name tag, specify a name tag for the Connect peer.

  5. (Optional) For Transit gateway GRE Address, specify the GRE outer IP address for the transit gateway. By default, the first available address from the transit gateway CIDR block is used.

  6. For Peer GRE address, specify the GRE outer IP address for the appliance side of the Connect peer.

  7. For BGP Inside CIDR blocks IPv4, specify the range of inside IPv4 addresses that are used for BGP peering. Specify a /29 CIDR block from the 169.254.0.0/16 range.

  8. (Optional) For BGP Inside CIDR blocks IPv6, specify the range of inside IPv6 addresses that are used for BGP peering. Specify a /125 CIDR block from the fd00::/8 range.

  9. (Optional) For Peer ASN, specify the Border Gateway Protocol (BGP) Autonomous System Number (ASN) for the appliance. You can use an existing ASN assigned to your network. If you do not have one, you can use a private ASN in the 64512–65534 (16-bit ASN) or 4200000000–4294967294 (32-bit ASN) range.

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

  10. Choose Create connect peer.

To create a Connect peer using the AWS CLI

Use the create-transit-gateway-connect-peer command.
