There should be no significant difference between v2 and v3 in these 
parts of BIRD. Does it happen only on 3.0-alpha1 or also on 2.0.12? 
Could you also please share with me your `show route all` output and 
configuration? (Possibly off-list.) I'll try to reproduce the issue here.

Thank you in advance.
