You can use the default property to specify a default server in the server-list section. Valid values are true and false.

The following JSON configuration file example shows a default server.

{
  "broker_list": {
    "Value": {
      "settings": {
        "server-list": [{
          "server": "viewserver0.mydomain.com",
          "default": true,
          "description": "View Server 0",
          "username": "User0",
          "desktopId": "RDS2012R2DC",
          "domain": "TestDomain0"
        }]}
    }
  }
}
