if an f5 is connected with 3 different interfaces with different IP subnet ( 172.24.1.0, 172.24.2.0, 172.24.3.0 ) to the L3 switch having a L3 Interfaces 172.24.1.1, 172.24.2.1, 172.24.3.1) still the f5 will be called as a one arm mode setup. please correct me if i m wrong. Any incoming VIP traffic if it hits the VIP i will route the traffic from the same interface back to the switch towards the pool servers.
Is there any glitch in the design.? expert advise please

Are you using a separate address subnet for the hosted VIPs? Are you planning to use SNAT? Will all pool members reside within the 3 subnets you have created and referenced above?
The following is a great resource I would read carefully and watch the video: https://my.f5.com/manage/s/article/K54312549.
adam_gibsDear Experts
I will use the different subnet for the hosted VIP, and also i will do the SNAT with self IP, the pool members will be having a different IP subnet that will be of inside DC subnet, as far as the f5 know the route it should not be a problem
example 1
Self IP: 172.24.1.2
VIP: 172.24.1.3
192.168.10.0 route will be pointed to L3 Switch IP address 172.24.1.1
pool members in data center subnet: 192.168.10.2,192.168.10.3,192.168.10.4.
SNAT with Self IP: 172.24.1.2
Example 2:
Self IP: 172.24.2.2
VIP: 172.24.2.3
192.168.11.0 route will be pointed to L3 Switch IP address 172.24.2.1
pool members in data center subnet: 192.168.11.2,192.168.11.3,192.168.11.4.
Thanks
