How to announce over OSPF only one IP address

[Radek]

Hello,
is it possible to announce over OSPF only one (or a few specific) IP address 
instead of the whole subnet?
If yes.. an ospfd.conf example would be appreciated.

$ cat /etc/hostname.vr3
inet 10.1.111.1 255.255.255.0

$ cat /etc/ospfd.conf
router-id 10.109.3.15
redistribute connected

area 0.0.0.0 {
        interface vr0
        interface vr3
}

Thanks, 
Radek
