Thanks a lot Nitass.

 

I took a look at the link you provided. It sounds like the solution which I am looking for.

 

Could you please take a look at my following questions regarding to this solution.

 

1. Which VS should I apply FastL4 profile?

 

The asymmetric routed connections in our scenario does not need load-balancing. F5 here is more like a router for the traffic between Vlan 10 and Vlan 11. Should I apply "FastL4 Profile" to "ip forwarding VS" only?

 

2. Since the solution required to disable "Packet Velocity ASIC", is there any performance impact here?

 

3. Is it a best practice to allowing asymmetric routed connection across multiple VLANs whenever F5 will be the default gateway for real servers and route the traffic across multiple VLAN? (it is very likely to have asymmetric routing in this case)

 

 

Very appreciate your help.
