Hi guys,

I have multipath enabled on bird6 running in old 1.6.8. I discovered that
the IPv6 prefix failed to be installed properly in the kernel with more
than 1 path and when multipath is enabled.

syslog message:

> Feb  9 23:54:31 x40-n bird6: kernel1 < replaced fcdf::/16 multipath
> Feb  9 23:54:53 x40-n bird6: kernel1: fcdf::/16: reinstalling
> Feb  9 23:55:53 x40-n bird6: kernel1: fcdf::/16: reinstalling

The IPv6 prefix is installed properly if I remove multipath in bird6:

> #    merge paths on;


But then it means the path won't be shared with the rest of the path.

syslog message:

Do you guys encounter this issue or is there any other configuration
needed? The multipath works well in IPv4/bird.

Thanks,
Jimmy
