Load Balancer Traffic Design without using Self IP
Hi everyone
I would like to know if anyone has used a setup that has one large subnet as an outside Vlan (for service VIP's) and it routes to all the different server vlans. Typically, we setup all the server vlans with Self Ip and Floating IP and then use the automap feature to move the traffic.
In this traditional model, we need to always reserve self IP and float IP in the vlans where the servers are built and to allow firewall rules for these IP and the subsequent "Outside" IP.
Is there a design where we can just have the traffic route to the servers? When I do not have a self IP for the vlan, it seems to just send the traffic via the default route.
Thanks

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.
