Hi Gert,
Thank you very much, for making it clear. I'm sorry i have given a wrong diagram here, it was for tun and works well.
Please find the diagram for tap https://pastebin.com/raw/fje2RFhc
I have mentioned every steps to establish connectivity from A to D, but it fails.
And once again thanks for your basic routing link, it might helps me to learn.
Thank you
Bipul

Your diagram is not making sense. The diagram shows "tun" and the config shows "--dev tun", but the routing table shows "tap0" - make up your mind. I'd stay with "tun" as your config shows, though, as you do not need tap unless you very clearly know *why*.
Then, you need routes toward the tap interface on the clients (otherwise, packets to "D" will not go into the tunnel) and most likely "D" will also need a route back.
This is all basic routing, so not really something for our bug tracker - look here to get started (read it thoroughly): http://www.secure-computing.net/wiki/index.php/OpenVPN/Routing - and if that does not help, the openvpn forum is better suited for user-to-user advice.
