  -[Post-Deployment Steps](#configure-domain) describes that in order to create a domain from which to create TCP routes, it must be associated with the TCP router group. A router group is a cluster of identically configured routers. Router groups are a mechanism to support reservation of the same port for multiple TCP routes, thus increasing the capacity for TCP routes. However, only one router group is currently supported. [Pre-Deployment Steps](#pre-deploy) describes how an admin user can configure the port range available for TCP routes in preparation for deployment.

   After deployment, you can modify the range of ports available for TCP routes using `cf curl` commands, as demonstrated with the commands below. These commands require an admin user with the `routing.router_groups.read` and `routing.router_groups.write` scopes.
   
  
positive.code: 
  1. Run `cf domains`. Verify that next to your TCP domain, `TCP` appears under `type`.
  
  ### <a id="configure-quota"></a> Configure a Quota for TCP Routes
  
  Since TCP route ports are a limited resource in some environments, quotas are configured to allow creation of zero TCP routes by default. After you deploy <%= vars.app_runtime_abbr %>, you can increase the maximum number of TCP routes for all orgs or for particular orgs and spaces. Because you reserve a route port for each TCP route, the quota for this resource is managed with the cf CLI command option `--reserved-route-ports`. For more information, see [Creating and Modifying Quota Plans](../adminguide/quota-plans.html).
  
  
negative.code: 1. Modify the `reservable_ports`:
  
      <pre class="terminal">
      $ cf curl \
      -X PUT -d '{"reservable_ports":"1024-1199"}' \
      /routing/v1/router_groups/f7392031-a488-4890-8835-c4a038a3bded
      </pre>
