Thanks for all the info, I was being a dumb a**. I was thinking that the BDR
would not know that the DR went down (because the loopback was always up). I
then remembered the hello packets. Thats what determines when an interface
is truely down or not (not sending hello packets). Thanks again
Loopbacks are used because they never go down or should never go down, to
make one the DR assign the highest loopback to the desired router. HTH's

In determining DR and BDR, OSPF will use the priority and the Router ID. I
can change the Router ID by creating a loopback with a higher ID (IP
address
Priority to me seems most useful for specifying which routers should never
be dr/bdr, most people would never want a 25xx to be dr.

You can have a better numbering/identificaton process if you use loopback
numbers, rather than some arbitraty IP.

not directly related to electing DR/BDR, but i use loopbacks for management.
it's the ip i associate in my hosts file for ssh access. also with
loopbacks i can control the ip for easier troubleshooting since i use a
numbering scheme where the 2nd octet indicates which physical location the
6 matches
