Hi All,
concerning the problem when running the "ip ru ls" command.
I faced with the same problem, and I solved it by making sure to include the following settings into the kernel configuration (2.4.18):

CONFIG_IP_ADVANCED_ROUTER=y    <===
CONFIG_IP_MULTIPLE_TABLES=y       <===
CONFIG_IP_ROUTE_FWMARK=y
CONFIG_IP_ROUTE_NAT=y
CONFIG_IP_ROUTE_MULTIPATH=y
CONFIG_IP_ROUTE_TOS=y
CONFIG_IP_ROUTE_VERBOSE=y
CONFIG_IP_ROUTE_LARGE_TABLES=y

The new kernel is then able to perform policy routing in the correct way (iproute2-010824)

ciao
- Alberto

I get the same error message also, but for a non-related reason, maybe. 
I am trying to run RX/TX load balancing on a RedHat a 6.2 download server. 
The version of iproute is iproute-2.2.4-2. 
When I invoke the command "ip rule list", I get the error message: 
RTNETLINK answers: Invalid argument 
Dump terminated 

My ifconfig output shows that everything is being processed by eth0. 

I even downloaded iproute2-current.tar.gz and ran a make, it did not seem 
to upgrade the /sbin/ip file.  OR, I did not configure it correctly. 

My /etc/rc.d/rc.local file reads: 
ip rule add from xxx.xx.xxx.xxx table 30 
ip rule add from xxx.xx.xxx.xxx table 31 
ip rule add from xxx.xx.xxx.xxx table 32 

ip route add xxx.xx.xxx.x/28 dev eth0 table 30 
ip route add xxx.xx.xxx.x/28 dev eth1 table 31 
ip route add xxx.xx.xxx.x/28 dev eth2 table 32 

ip route add xxx.xx.xxx.x/28 equalize nexthop dev eth0 nexthop dev eth1 nexthop dev eth2 

ip route add default via xxx.xx.xxx.x dev eth0 table 30 
ip route add default via xxx.xx.xxx.x dev eth1 table 31 
ip route add default via xxx.xx.xxx.x dev eth2 table 32 

ip route add default equalize nexthop via xxx.xx.xxx.x dev eth0 nexthop via xxx.xx.xxx.x dev eth1 nexthop via xxx.xx.xxx.x dev eth2

My /etc/sysconfig/network file has the following: 
NETWORKING=yes 
HOSTNAME=server.domainname.com 
DOMAINNAME=activision.com 
GATEWAY=xxx.xx.xxx.xxx 
GATEWAYDEV=eth0 
CONFIG_IP_ROUTE_MULTIPATH=yes 
CONFIG_IP_MULTIPLE_TABLES=yes 
CONFIG_IP_ADVANCED_ROUTER=yes 

Can the load balancing I am attempting work on RedHat Linux 6.2? 

Thanks, 
Robert.

Are you really sure they are the same? Did you run 'make oldconfig' on 
2.4.12? Do your modules work?
