It seems you trigger the problem that I met before, here is the link of disucssion:
http://www.spinics.net/lists/netdev/msg314717.html

You can try these patches to check if they resolve your problem:
7035870d1219 | 2015-05-03 | ipv6: Check RTF_LOCAL on rt->rt6i_flags instead of rt->dst.flags
653437d02f1f | 2015-04-28 | ipv6: Stop /128 route from disappearing after pmtu update

thanks,
Sheng

You are right, these two commits fixed my issue

Thanks
