IPv6 prefix is not stored to kernel when multipath is enabled in 1.6.8

[Douglas Fischer]

uuuhhh... 1.6?

This version has not been receiving updates for quite some time.
Definitely more than 5 years ago. And even before that, for a few years
version 1.6 was only receiving fixes.

I suggest you consider migrating to the current version of Bird2, which if
I'm not mistaken is 2.16.1
