clientRoutingPolicy

The client routing policy of the gateway. This policy controls which Availability Zones RTB Fabric uses to reach the gateway for the requester gateways that send traffic to it. Valid values are the following:

• AVAILABILITY_ZONE_AFFINITY: RTB Fabric routes each requester's traffic to gateway capacity in the requester's own Availability Zone when the gateway has capacity available there. Otherwise, RTB Fabric routes the traffic to gateway capacity in the other Availability Zones of the gateway.

• ANY_AVAILABILITY_ZONE: RTB Fabric routes each requester's traffic to gateway capacity in every Availability Zone that the subnets of the gateway span. The Availability Zone that the requester is in does not change this.

If you don't specify a value, RTB Fabric uses AVAILABILITY_ZONE_AFFINITY. To get the behavior of ANY_AVAILABILITY_ZONE, create the gateway with subnets in more than one Availability Zone. RTB Fabric does not support partial Availability Zone affinity, so PARTIAL_AVAILABILITY_ZONE_AFFINITY is not a valid value. For more information, see Configuring Availability Zone affinity in the Amazon Web Services RTB Fabric User Guide.
