As I was told back then the problem is with RedHat kerner. It was not compiled with corresponding option (CONFIG_IP_ADVANCED_ROUTER) After recompiling the kernel with this option iproute started to work OK.
Same problem still with RedHat 7.0 beta /sbin/ip rule list RTNETLINK answers: Invalid argument Dump terminated. Should CONFIG_IP_ADVANCED_ROUTER be added to kernel options?
davem says yes, added to list of things to do...
OK, in our source tree! Thanks.
