    I have this type of setup where there is no self-ip on the LTM and it works perfectly fine. Reason - All the IP addresses (VIP, Pool members) are advertised in the same routed protocol. I have not come through any issue with this design. It's configured in one arm mode and also uses snat pool.But on F5, you will have to set a default route for reverse traffic.

Hi, I have a setup that uses this. Have a front-end VS with a public IP and with selection in iRules it send the traffic to a back-end VS. This back-end-VS is APM enabled and are configured with private IPs that does not have any Self-IPs. The back-end VS then communicate with pools. Works perfectly.
