When creating a Knative service, we are able to configure only 'DisableRouteAnnotation' or 'EnablePassthroughRouteAnnotation' options [1].

If annotations are not set an 'edge' route with 'Allow' 'insecureEdgeTerminationPolicy' is created [2].

tls: 
  insecureEdgeTerminationPolicy: Allow 
  termination: edge 

 
On the other hand, when 'EnablePassthroughRouteAnnotation' is set through the annotation, a 'passthrough' route with 'Redirect' 'insecureEdgeTerminationPolicy' is created [3]:

tls: 
  insecureEdgeTerminationPolicy: Redirect 
  termination: passthrough

At this moment it is not possible to create an 'edge' route with 'Redirect' 'insecureEdgeTerminationPolicy'.

in this RFE it is requested to allow configuring 'insecureEdgeTerminationPolicy' when creating a Knative service.
