I have checked in 2 cisco 7609 routers i did not find the "ip load sharing per-packet" command itself on physical interface or logincal interface also.
IOS tried SRA and SRC releases:-
DD(config)# int mul 11
DD(config-if)#ip load-sharing ?
per-destination Deterministic distribution
I am not able disable the CEF in this platform also and "no ip route-cache" command is also not there.
The below link says the command is integrated on cisco SRA release
anybody has seen the same issue or is it a hardware limitation.
