First, what problem are you trying to solve? I understand that you
can advertise or not advertise the loopback, but why do you
specifically want to advertise it as a /24? In my past experience,
however, there were differences in advertising it as a /32, a /30,
and a shorter-than-/30.
There have been some modifications, over time, about how Cisco's
implementation of OSPF handles loopbacks. The developer with whom I
discussed them is no longer at Cisco, so I don't have an instant
source on the code, but probably can get one.
Before then, a couple of questions:
what do the following commands show with your configuration:
sh ip route 10.0.0.0
sh ip route 10.10.10.0
sh ip int 10.10.10.1
sh proto
