    I didn't do the justice just giving highlight of the architecutre in a diagram. Turns out netmask of detination for forwarding virtual server did not have /0 at the end so it was not "any"; but, was treated as /32.

Hi iamsajjad , thanks for the description. For this one, it would be helpful if you could paste snippets of the config (redact private info, IP's, etc) of the forwarding virtual, self/floating IP's, routes. A quick diagram could help as well. I think I understand the topology based on your description but a diagram would just help confirm. I'm assuming the packet capture is from the client?

Hello buulam thanks for going though my posting and trying to help.

.60 and .92 are the floating IPs on F5.

As requested here is the sketch of topology and routes from ACI and F5 (RD # 2).

From ACI or server in RIGHT VRF don't get reply if they ping server on LEFt or .60 floating IP of F5. Times out. Capture was done on F5.  It's true for other direction as well.
