IPV6 Multipath support

Hi All, I am using linux kernel 3.10.20, and tried to add multipath routes using the below commands. ip -6 route add default nexthop via 2222::1 dev eth1 weight 1 nexthop via 3333::2 dev eth0 weight 1. But when i run the traffic to the host reachable to both the interfaces, traffic is always going through eth1, which means the multipath routing is not working. Could you please let us know that do we have multipath support for ipv6 in linux3.10.20 kernel ? Thanks in advance.
