Hello,
 
I have some questions regarding load-sharing in the following scenario.
 
------------------------------------------------------------------------------------LAN1
  |                              |                                   |
eth0                         eth0                              eth0
(PC1)                       (PC2)                            (PC3)
eth1                          eth1                               eth1
  |                               |                                     |
----------------------------------------------------------------------------------- LAN2
 
Each machine has 2 ethernet cards but single IP address.
For each machine, eth0 and eth1 are in active-active mode for load sharing and are on different LANs
In this case, how to solve the ARP problem.
I tried to look for many available solutions on net regarding this. But could not find any perfect solution. Most of the solutions offer active-standby but not active-active.
Can anyone help in this case ? how to deal with ARP problem and achieve load sharing ? 
 
Thanking you in advance.
