Forwarding Virtual Server
Will still work as long as you have a SelfIP in the target network segment (BigIP is then directly connected). As anywhere else in networking, Directly Connected takes precedence over static and dynamic routes. BigIP will refer to routes only if SelfIP is absent.

Hi Hannes,
Thanks for your reply, I got your point and it makes logic that if F5-unit has direct connection in the target network segment the communication will work but if the target network segment is not a directly connected network in that case what will happen does F5 unit only refer to the routes or does it also refer to other forwarding VS that can make this reach-ability possible?

I did similar test more than a year ago. Hopefully I recall the details correctly.
Another VS will not be used as a backup. Virtual servers are strictly client-side and only one Virtual Server can match for one connection. If theres a default route in place, then that will be used as last resort. Obviously, default route is unlikely to get the request to right recipient, thus client is more than likely get a connection timeout error (connection drop). If there's no default route to refer to either, then BigIP will respond with TCP RST and client will get a "connection has been reset" error. Outcome for client will be exactly the same as if there were no pool members available for a standard type Virtual Server.
