Rick,
It looks like the other router is some corrupting your route to
204.212.248.10. Your router still has a route to the destination
network, otherwise you would get '.'s instead of 'U's. So, your
router is sending it on to someone else who is confused.
Did you give it a little while for convergence to finish, especially
if you are using a distance vector routing protocol?
You may want to turn off the romote 2500, trace through to
204.212.248.10, print a copy of 'sh ip route' on all the routers that
you pass through, turn on the remote 2500, wait a few minutes, trace
again, print the routing tables and compare them. Look for routes
that have changed into weirdness.
I'm assuming that you've followed all the normal ip rules: no
duplicate or overlapping subnets, if distance vector routing: only one
mask per classful address and no discontiguous nets.
Fun problem! If you get it working, let me know the resolution!
Hope this helps.

Do you have a 'timers basic' parameter configured on your routers?
I've seen this type of thing happening when one router's timers basic
values are set differently from the others (or isn't configured at all
in that particular router).)
