Is 'Auto Last Hop' feature used exclusively by F5?
Do other vendors have similar functionality? Linux kernel, Cisco?
I.e. F5's 'nPath routing' is knows as 'Direct Server Return' in Cisco world.
Maybe 'ALH' has a different name as well?
i am not aware of the similar feature in other vendors. anyway, this blog mentions it is also called "reverse persistence".

I think Netscaler supports it too (MAC-Based Forwarding).
I think BlueCoat has something like that too.
