Can a floating IP be the next hop for routing?

Hello, Recently tried using HA in Route mode. Here is my structure : I thought floating ip can be the next hop of Route. So I set the next hop in Client Route as & Switch's is 2.2.2...

    So from client you are attempting to reach server on on tcp/80 or possibly tcp/443? If your routing is in place and you can indeed ping from and the other way around then it could be your forwarding virtual server that is not allowing the traffic to pass through the F5. You should be able to perform a tcpdump on the active F5 of the following and see where the traffic is going.

    tcpdump -nni 0.0:nnp host <source_IP> and port <destination_port>

    tcpdump -nni 0.0:nnp host and port 80

    In your topology I would make the switch an L2 switch for the VLAN that sits behind the F5s and have the F5s and server be in subnet with the gateway for the server being If forcing the switch to be in routed servse another purpose for you then keep it but if not I wouldn't do it because it adds unneeded complexity without much benefit. If your intent is to be able to manage the switch by an IP you can always IP it from that same subnet and reach it.
