Description of problem:
In OSE 3.0.2 you can expose routes depending on a few things (https://docs.openshift.com/enterprise/3.0/whats_new/ose_3_0_release_notes.html#ose-3-0-2-0):

* Pass --namespace to the router command to select routes in a single namespace.
* Pass --labels=<selector> or --fields=<selector> to select only routes with the provided labels or fields.
* Pass --project-labels=* to show routes in all labels that the router’s service account is granted access to, --project-labels=<selector> to filter that list by label, or --namespace-labels=<selector> to filter all labels when the router service account has that permission.


But in OSE 3.1.1.6, 
--namespace can be used as a option in oadm cmd, but it is not displayed in oadm router --help page
--project-labels and --fields options can not be used as a option in oadm cmd and not displayed in oadm router --help page
only --labels works fine to be  used as a option in oadm cmd and displayed in oadm router --help page

Version-Release number of selected component (if applicable):
oc v3.1.1.6
