Also, I have found for myself, and would like to reiterate, that most
people don't realize the command only applies to internal OSPF learned
routes as well. Just like with EIGRP and this command.
If I'm wrong then I need to really go look at this again, but that was a
huge eye opener to me...
Especially when I'm banging on the keyboard at 1am trying to get
external routes to change their AD this way... There is only so much
banging my keyboard can take before it just wont work. 8)

Swaroop,
The wildcard mask is simply used to determine which bits in the
address field are significant. For example, to change the distance to
100 for routes matched in access-list 1 from all sources the syntax
would read:
distance 100 0.0.0.0 255.255.255.255 1
To match routes only learned from 1.2.3.4:
distance 100 1.2.3.4 0.0.0.0
If your syntax worked by matching the access-list of the
neighbor then it was just coincidental that the originating address and
the neighbor address fall within that range.
HTH,
