  You must edit the BOSH deployment manifest to include an instance group for each set of routers.
  
  The sample [BOSH v2 manifest](https://bosh.io/docs/manifest-v2.html) snippet below includes an additional instance group for the isolated routers, associated with the isolated BOSH AZs. As a result, router instances will be configured with IP addresses from the isolated subnets.
  
  <p class="note"><strong>Note</strong>: For a high-availability deployment assign each instance group to at least two Bosh AZs that correspond to different IaaS AZs. Use at least two instances of each instance group.</p>
  
  <p class="note"><strong>Note</strong>: When deploying with a BOSH v2 style manifest, that leverages `instance_groups`, you must enable UAA to differentiate between links exported by the Gorouters, as it will only accept connections from one instance group of Gorouters. As you may have multiple isolation segments, we recommend renaming the instance group used for the system domain. You will also need to specify the name of the link that UAA consumes the link from.</p>
