Each VPC in the hub-and-spoke architecture can connect to the transit gateway to gain access to other connected VPCs. AWS Transit Gateway supports traffic for both IPv4 and IPv6. + +In Oracle Database@AWS, an ODB network supports a peering connection to only one VPC. If you connect a transit gateway to a VPC that is peered to an ODB network, you can connect multiple VPCs to this gateway. Applications running in these VPCs can access an Exadata VM cluster running in your ODB network. + +The following diagram shows a transit gateway that is connected to two VPCs and one on-premises network. + + + +In the preceding diagram, one VPC is peered to an ODB network. In this configuration, the ODB network can route traffic to all VPCs attached to the transit gateway. The route table for each VPC includes both the local route and routes that send traffic destined for the ODB network to the transit gateway. + +Note the following limitations of Amazon VPC Transit Gateways for Oracle Database@AWS: + + * Amazon VPC Transit Gateways doesn't offer native integration to use an ODB network as an attachment. Therefore, VPC features such as the following aren't available: + + * Resolution of public DNS hostnames to private IP addresses + + * Event notification for changes in the ODB network topology, routing, and connection status + + * Multicast traffic to the ODB network isn't supported. + + + + +In AWS Transit Gateway, you're charged for the number of connections that you make to the transit gateway per hour and the amount of traffic that flows through AWS Transit Gateway. For cost information, see [AWS Transit Gateway pricing](https://aws.amazon.com/transit-gateway/pricing/). + +###### To configure a transit gateway for Oracle Database@AWS + + 1. Add CIDR ranges to your ODB network for the VPCs and on-premises networks that you plan to attach to your transit gateway.
