When I try to add an ip rule for Ipv6 in my linux system, it errors out.

ip -6 rule add fwmark 0xfab lookup 0xf RTNETLINK answers: Address family not supported by protocol I did checkout the "ip rule" code, it issues a netlink message to the kernel. Probably I need to load some module. Does anyone have any idea what needs to be done to fix this?

I am using linux 2.6.37.3 built from kernel sources.
