  -Running `curl  go-app.istio.example.com` results in 50% of the requests going to `go-app` and 50% of the requests going to `dora`.+If `go-app` has a weight of 9 and `dora` has a weight of 1, then running `curl  go-app.istio.example.com` results in observing 90% of the requests go to `go-app` and 10% to `dora`.
positive.code: 1. Get the GUID of the route:
  	
  	```
  	cf curl /v2/routes?q=host:APP-NAME
  	``` 
  	The GUID of the route is located after `"metadata": {"guid":`. 
  
  1. List the route mappings associated with the route:

  <p class="note"><strong>Note</strong>: This feature does not yet have cf CLI integration. The steps for updating a routing weight require you to curl the Cloud Controller v3 API.</p>
  
  You can configure routing weights when creating or updating a route mapping, Follow the procedure below that corresponds to your use case. 
  
  You can repeat the steps for each app that you want to receive a portion of requests at the same route.  
  
  ### <a id="new"></a> Create a New Route Mapping
  
  This procedure describes how to use `cf curl` to map a route to an app and assign a weight.  
  
  1. If you do not already have one, create a route. The route must use the shared domain created for Istio:
  
  	```
  	cf create-route SPACE-NAME SHARED-ISTIO-DOMAIN -n HOSTNAME
  	```
  	Where:
  	* `SPACE-NAME` is the space in which you want to create the route. 
  	* `SHARED-ISTIO-DOMAIN` is the shared Istio domain configured by your operator. 
  	* `HOSTNAME` is the hostname to use for creating the route. The format of the route is `HOSTNAME.SHARED-ISTIO-DOMAIN`. 
  
  1. Get the GUID of your route:
  
  	```
  	cf curl /v2/routes?q=host:HOSTNAME
  	```
  	Where `HOSTNAME` is the hostname you specified when creating the route.
  
  1. Get the GUID of the app that you want to map the route to:
  
  	```
  	cf app APP-NAME --guid
  	```
  
  1. Create a route mapping and assign a weight:
  
  	```
  	cf curl /v3/route_mappings -X POST -d '{"app_guid": "APP-GUID", "route_guid": "ROUTE-GUID", "weight": WEIGHT}'
  	```
  	Where:
  	* `APP-GUID` is the GUID you got previously
  	* `ROUTE-GUID` is the GUID you got previously
  	* `WEIGHT` is an integer from 1 to 128
  
  ### <a id="existing"></a> Update an Existing Route Mapping
  
  This procedure requires that you have mapped an app to a route in the shared Istio domain either using `cf map-route`, or `cf curl` as described in [Create a New Route Mapping](#new) above. 
  
  To update an existing route mapping with a new weight, do the following:
  
  1. Get the GUID of the app:
