We are using OSPF on PC not for routing purposes: those servers are DNS,
web, mail and other clusters. So on each server if it's alive: server is
up, all backends are availiable and so, servers are anouncing "service
ip" to OSPF. If there are some problems with backends then PC in cluster
stop redistribute "service ip" or change metric for it.

So for that reason I think that NSSA is better than anything else.
I'm also thinking about using BGP for that purposes but we'he already
have working OSPF-scheme and it will be nice if we could continue using it.
