  -For metrics emitted by the gorouter, metrics can be distinguished by the name of the job.
  +For metrics emitted by the Gorouter, metrics can be distinguished by the name of the job.
   For example, the following line is a metric emitted on `uptime`:
   
   ```
  
positive.code: <tr>
  <td> segments </td>
  <td> none </td>
  <td> Invalid combination; deploy will fail. </td>
  </tr>
  <tr>
  <td> segments </td>
  
negative.code: 
  The three supported values of `routing_table_sharding_mode` are `all`, `shared-and-segments`, and `segments`.
  
  * `all`: All routes will be registered. This is the default mode to preserve Gorouter's existing behavior.
  * `shared-and-segments`: Both routes configured with manifest property `isolation_segments` and routes without an isolation segment specified will be registered.
  * `segments`: Only routes for the configured isolation segments will be registered.
  
  You can provide a list of isolation segments using the manifest property `isolation_segments`.
  
  The following table describes the behaviors that you can achieve with these two properties:
