_tcp_modify_ports.html.md.erb

Configure the `routing_api.router_groups` manifest property with the same range of ports that you configured your load balancer with in step three, above.

  <pre>
  routing\_api.router\_groups:
  - name: default-tcp
    reservable_ports: 1024-1123
    type: tcp
  </pre>

See the <a href ="https://github.com/cloudfoundry-incubator/routing-release">CF Routing Release Github</a> page for more information. To modify the ports after you have deployed, see the [Post-Deployment steps: Modify your TCP Ports](#modify-ports) topic below.
