Info about load balancing in cisco routers and switches!!

Hi to all,

I need some help regarding some information about per-packet load balancing in Cisco routers and switches. By "per packet" load balancing I mean to say that the packets forming part of one particular connection are forwarded to different machines, in a round-robin manner. I know that there is something called stateless load balancing where load balancing is based on mac pair or ip pair hash, but this is not what I want. I wanted to know if there are Cisco routers and switches that support the per-packet load balancing scheme i'm talking about (not stateless load balancing).

I have also heard that Cisco routers can do per-packet load balancing on a router interface by issuing the following command:

Router(config-if)#no ip route cache

My network topology is as follows:


|A|-------| |
| |
|B|-------| | | |
|Switch |-----|Router|
|C|-------| | | |
| |
|D|-------| |

I wanted to ask whether the above command will load balance traffic from the internet onto the four PCs (A,B,C,D) connected to the switch on a per-packet basis (i.e plain round-robin irrespective of the connection to which packet belongs to). What I basically want to do is that packets pertaining to one particular connection get load balanced in a round robin fashion over the 4 PCs. Will the above command do that or should I go for etherchannel?

Any help will be much appreciated..

Warm regards,
