Exp : AWS VPN CloudHub and Redundant Customer Gateways

You can establish multiple VPN connections to a single virtual private gateway from multiple customer gateways. This configuration can be used in different ways; you can have redundant customer gateways between your data center and your VPC, or you can have multiple locations connected to the AWS VPN CloudHub.

If you have redundant customer gateways, each customer gateway advertises the same prefix (for example, 0.0.0.0/0) to the virtual private gateway. The gateways will be used in an active/active mode, but if one customer gateway fails, the virtual private gateway directs all traffic to the working customer gateway.

If you use the AWS VPN CloudHub configuration, multiple sites can access your VPC or securely access each other using a simple hub-and-spoke model. You configure each customer gateway to advertise a site-specific prefix (such as 10.0.0.0/24, 10.0.1.0/24) to the virtual private gateway. The virtual private gateway routes traffic to the appropriate site and advertises the reachability of one site to all other sites.

To configure the AWS VPN CloudHub, use the AWS Management Console to create multiple customer gateways, each with the unique public IP address of the gateway and a unique autonomous system number (ASN). Then create a VPN connection from each customer gateway to a common VPN gateway. Use the instructions that follow to configure each customer gateway to connect to the virtual private gateway.

To enable instances in your VPC to reach the virtual private gateway (and then your customer gateways), you must configure routes in your VPC routing tables. For complete instructions, see the Amazon VPC User Guide. For AWS VPN CloudHub, you can configure an aggregate route in your VPC routing table (for example, 10.0.0.0/16), and use more specific prefixes between customer gateways and the virtual private gateway.
