[quagga-users 14432] Redundant Service IP on loopback

I found a link about this a couple months ago but apparently I didn't
save it, so I'm going to have to ask...
The article I found described how to set up the IP for some service
(i.e. DNS) on the loopback interface of two identical servers and then
use BGP to distribute route advertisements with different metrics such
that if the server with the lower metric fails or is rebooted the
traffic will go to the other server.
My main goal here is services such as DNS and LDAP were the service is
primarily used by other hosts/servers on the same subnet. I'm not sure
if the original scheme (above) assumed that there was a router involved,
but in this case there is no router.
Any guidance would be sincerely appreciated.
