  VirtualService and destination rule for echo service:</p>
  
  <p>My calling <code>echo-svc:8080</code> and <code>echo-svc:8080/v1</code> from my another virtualservices , I'm not able to do route in specific version.</p>
  
  <p>When making request from another virtualservice: <code>echo-svc:8080/v1</code> or <code>echo-svc:8080</code>, I'm getting response from both the subsets. </p>

  <p>If I'm attaching my echo-service to gateway and then making service to <code>v1</code> endpoint via istio-ingress, my all requests are routed to required k8s service, but if it's internal(echo service not attached to gateway) envoy is not routing the requests to required k8s service..</p>
