LARTC - May 2005 - ip route command query regarding multipath

hi
  I am working on IPv4 equal cost multipath with caching support
on 2.6.12 kernel. I have successfully created multipath route by command :-

/sbin/ip route add 10.200.0.0/16 scope global equalize \
nexthop dev eth0 weight 1 \
nexthop dev eth1 weight 1

But I can not specify multipath algorithm, e.g. : round robin algorithm
or random algorithm.
Can anybody please suggest me correct command or  command 
arguments for ip.

Thanks & Regards
Pravin

Ripv2 supports vlsm and can load balance (per packet / per dest) over
as many as six equal cost paths.I dont know if this helps.
