  In this example, you can also unmap the route from one of the apps and observe 100% of the requests going to just one app, which simulates a migration.
  
  ### <a id="considerations"></a> Considerations for Working with Routing Weights
  
  Consider the following when working with routing weights:
  
  * The default weight is 1. This means that if multiple apps are mapped to the same route and their weights are not updated, traffic is equally distributed between them.  
  * The percentage of requests described above is not applied exactly, but over time the requests reflect the percentage.
  * You cannot set a weight to 0. You can stop weighting traffic by deleting apps or unmapping apps from the route. 
  * You cannot exceed 100 routes mappings for a particular route. This could result in some apps not receiving any requests.
  
  
  ## <a id="procedure"></a> Configure Routing Weights
  
  <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. 
  
  
negative.code: 	cf curl /v3/route_mappings -X POST -d '{"app_guid": "APP-GUID", "route_guid": "ROUTE-GUID", "weight": WEIGHT}'
  	```
  	Where:
  	* `APP-GUID` is the app GUID you recorded previously
  	* `ROUTE-GUID` is the route GUID you recorded previously
  	* `WEIGHT` is an integer used to calculate the percentage of requests the app receives. You can enter a value from `1` to `128`. See [How Weights are Calculated](#calculation) above.
