Hi Maria, Thanks for your update. I have just run the test in another box running BIRD 2.0.12. I encountered the same issue. The IPv6 prefix is not installed in the kernel if there is more than 1 equal path available. This is what I see in the log:

Basically I have just configured inside protocol kernel.
