How to set OSPF dummy0 propagation cost?

[Petr Boltík]

Hello,

I have a simple question for most of you, .... I have Bird 2.0.7 and using
multiple dummy interface (lo0 and lo1) with /32 IP address. I can propagate
this interface using

# R1 with lo1:
interface "lo1" {
   cost 2000;
   stub;
};

# R2 with lo1:
interface "lo1" {
   cost 10;
   stub;
};

#router 3 get the same cost for /32 route from R1 and R2

question is - how to propagate the lo1 address from multiple devices with
the different costs? Attribute "cost" not makes any changes. What I miss?
Thank you.
