+If you want to use a gateway with a shared listener host (IE the same hostname on more than one gateway instance). Then you should use the following configuration:

+EOF
+```    
+
+The loadbalancing section here has the following attributes:
+
+- **Weight:** This will be the weighting used for records created for hosts defined by this gateway. It will decide how often the records for this gateway are returned. If you have 2 gateways and each DNSPolicy specifies the same weight, then you will get an even distribution. If you define one weight as larger than the other, the gateway with the larger weight will receive more traffic (record weight / sum of all records).
+- **geo:** This will be the geo used to decide whether to return records defined for this gateway based on the requesting client's location. This should be set even if you have one gateway in a single geo. 
+- **defaultGeo:** For Azure and AWS, this will decide, if there should be a default geo. A default geo acts as a "catch-all" (GCP always sets a catch-all) for clients outside of the defined geo locations. There can only be one default value and so it is important you set `defaultGeo` as true for **one** and **only one** geo code for each of the gateways in that geo.

 > **Note:** If you have followed through this guide on more than 1 cluster, the DNS record for the HTTPRoute hostname will have multiple IP addresses. This means that requests will be made in a round robin pattern across clusters as your DNS provider sends different responses to lookups. You may need to send multiple requests before one hits the cluster you are currently configuring.
