ERR when redistributing to OSPF NSSA

[Tapio Haapala]

On our case this not harmless at all. We have searched what cause 
distribution problems when network link goes down and up. On our setup 
we distribute each computer as /32 route and on some cases when nic hang 
and reset it self or link goes down we lost /32 routes and it get fixed 
when we restart bird.
