    If I'm understanding your question correctly, you cannot have two VIPs with the same IP address and port. There is a precedence that the F5 uses when accepting network traffic:

     

    1. Existing session in session table
    2. Packet Filter
    3. Virtual Server (https://support.f5.com/csp/article/K14800)
    4. SNAT
    5. NAT
    6. Self-IP
    7. Deny

    The third item on this list->Virtual Server has a precedence as well: https://support.f5.com/csp/article/K14800. That precedence would not allow two virtual servers to share the same IP address and port.
