It may also be necessary to rebuild the kernel.
CONFIG_IP_ROUTE_MULTIPATH
  Normally, the routing tables specify a single action to be taken in
  a deterministic manner for a given packet. If you say Y here
  however, it becomes possible to attach several actions to a packet
  pattern, in effect specifying several alternative paths to travel
  for those packets. The router considers all these paths to be of
  equal "cost" and chooses one of them in a non-deterministic fashion
  if a matching packet arrives.
