I'm new to OpenShift. I have two projects|namespaces. In each I have a rest service. What I want is service from NS1 access service from NS2 without joining projects networks. Also SDN with multi tenant plugin.

I found example on how to add external services to cluster as native. In NS1 I created an Endpoint for external IP of Service form NS2, but when I tried to create a Service in NS1 for this Endpoint, it failed cause there was no type tag (which wasn't in example also).

I also tried ExternalName. For externalName key my value was URL of router to service in NS2. But it doesn't work pretty well, cause it always returns me a page with Application is not available. But app\service works.
