Hi iamsajjad, if I'm imagining the diagram properly, you have all the "back end" stuff in one route domain, correct? Even if all the routing is set up correctly, remember that a route is only the infrastructure you need to forward traffic, you still need a forwarder to allow it. You mention you have a wildcard virtual server for icmp, but does that exist in both route domains?
